    "We've done tons of user testing on this, and it turns out it doesn't work. Touch surfaces don't want to be vertical. It gives great demo but after a short period of time, you start to fatigue and after an extended period of time, your arm wants to fall off. it doesn't work, it's ergonomically terrible."

      “Who wants a stylus? You have to get ’em and put ’em away, and you lose ’em. Yuck. Nobody wants a stylus. So let’s not use a stylus. We’re going to use the best pointing device in the world. We’re going to use a pointing device that we’re all born with—born with ten of them. We’re going to use our fingers.”

      — Steve Jobs, 2007

      (8 years before the introduction of the Apple Pencil)

      • zuhsetaqi 2 hours ago
        When Steve Jobs said that, he was talking about a stylus as a main or even only input device. And he is still right about it. The Apple Pencil for the iPad never was a main input device but an alternative.
        • overfeed 47 minutes ago
          That wasn't the only time Jobs trashed a category Apple didn't currently have a model for, but was actively developing; he also slurred 6-inch Android phones as "Hummers", and mocked the 7-inch Android tablets as "too small" before Apple launched its iPad Mini.

        The Pencil isn’t a stylus. At least not primarily. It’s designed for freehand. This is probably why they insisted on it charging via Lightning by removing its end cap. They didn’t want people getting ideas.

        And here we are, and the Pencil STILL doesn't work on the defectively oversized trackpads on Apple laptops.

        So... we're talking about more than one blunder here.

          Many (including me) argue that Apple sells the best trackpads ever made, the size being a key attribute.

      I had several PCs with touch screen and this absolutely true. Even intermittent use is not something I did, it’s just too inconvenient to ever become a habit, so the few times it’d be great, I don’t think about it being there because it’s not in my active list of affordances.

        Then, on the rare occasion where you do use it, you end up with a single finger smudge that lasts until you find the will to clean it.
      • ErroneousBosh 1 hour ago
        The problem with touchscreen laptops is you have to reach over the keyboard and trackpad to actually touch the screen to make it work, and that's physically uncomfortable and kind of inconvenient.

        The answer is to make them fold flat so you're just looking at the screen with the keyboard facing away from you (and, ideally, disabled by a switch in the hinge so when you put it down you don't zkjltohtrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrolkmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

        Then, of course, it becomes annoying and inconvenient to use in a different way, but at least you get really really good at replacing the little flexi PCB ribbon that connects the screen through the hinge.

        • overfeed 35 minutes ago
          Spurious keyboard inputs and broken ribbon cables may have been issues in 2003, but tablet-mode laptops made in the last 15 years face no such issues; e.g. the many generations of the Lenovo Yoga series in that period. In 2026, even 7mm-thick phones can have reliable 180°/-180° folding screens - laptops have a lot more volume to play with and fewer lifetime open/close events.

          Apple's problems with touchscreen laptops are not mechanical; if Apple were to make a decent touchscreen laptop - say a 12" MacBook Air, it'd have a 360° hinge and cannibalize iPad sales, so they don't make that device to preserve the segmentation motivating people to buy both devices.

        • VerifiedReports 1 hour ago
          It's totally pointless, because the trackpad is already a touch device... and you use it to manipulate a precise cursor that doesn't block your view of what you're working on.

      I wonder what people will say when Apple releases the touch screen MacBook later this year then.
      • VerifiedReports 1 hour ago
        They'll say it sucks ass, and they'll be right.

        Touchscreen computers have failed for a reason.

        Then again... so did "transparent" UI, which Apple just exhumed.

        That it’s a silly idea, mostly. But some people will love it. As with anything Apple does.

      Nobody forces you to use touchscreen exclusively?
      • onion2k 2 hours ago
        If that's the case then the interface will remain a compromise that has to work for both point and touch, and ends up being suboptimal for both. Touch input necessitates bigger hit targets, lots of additional negative space around important buttons rather than groups, and a much lower information density on anything that has a click/touch handler like a list in order to avoid accidental presses. Apps need to be written with a touch UI in mind to work well.
        • cosmic_cheese 1 hour ago
          It will likely compromise anti-glare performance too, since an oleophobic treatment will be required for the screen to not instantly be covered in a haze of fingerprints. For someone who has no use for touch this is a strict downgrade.

          The only way touch on MacBooks can make a shred of sense is if it’s a non-default option in the configurator, much like the current nanotexture matte option.

      • VerifiedReports 58 minutes ago
        You say that now. And yet Apple now forces you to use shitty Bluetooth headphones to listen to its most popular music player.

      I have used a couple of laptops with touchscreens, and the experience was awful, even with the latest technology. If Apple gave us an iPhone or iPad-quality touchscreen on MacBooks, I am 100% sure the experience would be perfect.

        I have a laptop with a touchscreen that I regularly forget is a touchscreen until I accidentally touch it.
        • Fezzik 1 hour ago
          Same. My work laptop has a touch screen and every now and then, when I remember that fact, I’ll use it to scroll through a few pages of a PDF. It gives me a chuckle because it’s so inefficient and inaccurate… then I immediately revert to my click-wheel mouse.
    • neya 4 hours ago
      Yeah, but this was also strategically in Apple's interest to sell the iPads with nerfed up iPad OS as a separate line up. I love Steve Jobs and all, but this did NOT age well. The millions of people using Surface and Surface Pro will absolutely disagree with this take.
  • dotBen 10 hours ago
    I wouldn't want a touchscreen MBP even if it was free, anyone else feel similar?

    I don't get the draw - we already optimize for keyboard commands to avoid living our fingers over to a touchpad. Why would I want to start clicking on my screen?

    If you're using your computer for tasks (rather than entertainment) and you're not a visual designer, I don't get why Apple are apparently going to be putting them into the new MBP line later this year.

    • AussieWog93 4 hours ago
      I feel like the point isn't "there should be a touch screen MacBook" but more "holy shit we simulated a working touch screen by looking at reflections coming off the glass, isn't that cool".

      I don’t understand touchscreens on laptops that aren’t designed to fold flat. It’s got the feel of finger painting an unconstrained birthday balloon.
      • dwedge 8 hours ago
        I had a laptop that folded to 180, without touch screen, and had a webcam hidden under F7 so it either looked straight up your nose or showed your huge fingers
      • samplatt 5 hours ago
        You're essentially holding a large tablet upright, but all the weight is taken up up the base. Rather than finger-painting, try holding it on both sides like a tablet or gamepad and operating with thumbs.

        Scrolling/controlling checkboxes and switches feels GREAT. Depends entirely what you're using it for.

    • bitmasher9 10 hours ago
      Sometimes, if I’ve been using my iPad for awhile and switch over to my MBP, I might reach out and touch the screen out of habit. I can’t be the only one.
      • antonymoose 9 hours ago
        I had the opposite problem when work issued me a ThinkPad - I would accidentally brush my screen with my caveman knuckles once a day and somehow nuke a dozen lines of code.

      • bruckie 6 hours ago
        My kids do this all the time. They also use the touchscreen in conventional laptop configuration (not folded-flat tablet mode) on their Chromebooks all the time. It's bizarre to me. I'm always trying to get them to use the keyboard, but they don't care. Example: enter password on the keyboard, then tap the log in button on the screen with their finger, rather than just pressing enter. ¯\_(ツ)_/¯
        • egeozcan 3 hours ago
          My 3 year-old never had access to tablets or phones but sees us using phones all the time. So when he gets curious and touches the laptop screen (something he does with our phones occasionally as well), he's shocked to see it doesn't react.
        • jval43 2 hours ago
          I do this on my iPad with Magic keyboard and I'm a die hard command line user otherwise.

          I think the reason I started doing it on the iPad is that the keyboard focus is sometimes inconsistent, so clicking or tab-tab-tab-enter is slower and less reliable vs. just touching the screen. Definitely feel the gorilla arm though.

    • dwedge 8 hours ago
      While I'm the same and totally agree with you, the few times I've been using touchscreen I find the habit sticks so hard that for days I keep touching my macbook screen, so there is definitely some subconscious desire for this (or I would have defaulted to using the trackpad even if my brain thought touch was available)
    • post-it 10 hours ago
      > I don't get why Apple are apparently going to be putting them into the new MBP line later this year.

      Apple has apparently being going to put a touchscreen in a laptop every year since the iPad came out, and it's never materialized.

      • xmprt 10 hours ago
        Previously, those were rumors from enthusiasts who wanted to see it. Now it's an internal leak so there's a lot more credibility to those rumors.

            It looks like those leaks aren't too far off what I'm saying. Deadlines slipping by 1-2 years isn't way off especially for such a new/different product direction. And the rumor also said "could" which means even internally, it wasn't a strong claim.

              Yes and it's an article about a leak 3 years ago. And there were more "leaks" before that. I just can't be bothered to research and link the obvious to argument against an "opinion".
    • radley 10 hours ago
      It just feels ancient and weird now that I can tap every screen I own, except my Mac. I don't want to replace the Mac's keyboard & mouse with a touchscreen, I would simply like it to support touch.

      (This also made me realize the impending obsolescence of the Studio Monitor XDR: no touch support.)

    • christophilus 6 hours ago
      I have 2-3 old touchscreen laptops lying around. The touchscreen is useless to me. Worse than useless. If I ever use it, it’s accidentally, and I end up annoyed.
    • emmelaich 5 hours ago
      Sometimes I feel the urge to do some art, and the bigger surface might allow that. Perhaps in lieu, make a bigger trackpad.
    • thesuitonym 10 hours ago
      Macs are definitely not optimized for keyboard commands. If you feel the software you use is keyboard optimized, odds are it's not really Mac software.
      • allthetime 5 hours ago
        Absolute base line example.

        Copy text in terminal

        Mac: command+c

        Linux/windows: ctrl+shift+c (unless you want to cripple proper ctrl+c functionality in which case you can (maybe) activate it from a UI menu)

        The command key on Mac is somewhat magical and engages in all sorts of productivity and finger efficiency related context switching so that you can do more with less physical movement.

        I’m genuinely curious who you think does it better

      • jonhohle 7 hours ago
        macOS has been one of the best keyboard OSes for over a decade, maybe longer. Nearly everything is bindable without additional software or third party apps. This can be done on globally or app-specific. A lot of this comes from the deep script ability that used to be a priority but has fallen by the wayside in recent years.
      • 9dev 9 hours ago
        Huh? Of all the wonky shit about my Mac, the flawless keyboard navigation is really none of that
        • dwedge 8 hours ago
          I'm surprised you feel that way. I fight with my mac every day for one reason or another. At least it's not as bad as the days where some software used Cmd + letter and some used ctrl +letter, but for instance Cmd tab will switch to the wrong window when I go back and I have to use the mouse. Window switching in general is a lot harder if you only have the keyboard because the laptop is docked without a magic trackpad
          • codesnik 7 hours ago
            strange. Some keyboard shortcuts in os x are kinda weird and not intuitive to linux or windows users, but they are there. It's totally possible to use mac without trackpad. even cmd+tab switcher has a lot of hidden (but googlable) things: while still holding cmd after initial cmd+tab, you can close apps with q, switch to other apps with tab and (cmd+)shift+tab or left/right arrows, show app windows with down, etc. There's also a cmd+` for switching between one app's windows. I still find that distinction weird from usability perspective, but it's not too hard to adapt to it.
        • __MatrixMan__ 7 hours ago
          Really? I find that on MacOS apps are very inconsistent about whether popping open a menu shows me hints for selecting items in that menu. Those same apps are consistent about it on Linux.

          And then there's the bonkers window manager which can't move focus directionally (e.g. Super + left) and so you have to fall back to Cmd + tab tab tab tab but even then there's no consistency about whether you're switching between app instances or windows instances within the same app...

          • cosmic_cheese 1 hour ago
            Display of shortcuts in menus is the responsibility of the app developer (especially in the case of use of foreign UI toolkits). If you don’t see them it’s because its dev dropped the ball and the Mac version is an afterthought.
            • __MatrixMan__ 53 minutes ago
              I think its more about priorities. I expect touch related features to be a bit rough on Linux and I expect the same for keyboard focused things on Mac.
          • JSR_FDED 6 hours ago
            Cmd+Shift+Tab goes in the opposite direction.
            • __MatrixMan__ 1 hour ago
              Yes but what goes left, right, up, or down?
        • paxys 7 hours ago
          Specific applications sure, but the base OS interface is unusable without a trackpad.
          • Jeremy1026 6 hours ago
            Cmd+Space to open spotlight, type in the first 3 or 4 letters of whatever you're trying to do (an application to open, or a system setting to change) and then Return gets me about where I need to go most of the time. Cmd+Tab and Cmd+` for window selection. I don't do much else on the OS itself so my bases are covered.
        • devmor 9 hours ago
          “Flawless” is absolutely the opposite of how I’d describe the third class keyboard navigation in MacOS.

          It’s actually more intuitive to use a magic keyboard on the iPad than on the desktop OS.

          • sitharus 9 hours ago
            What do you find missing from macOS keyboard navigation?

            I've been using macs since the 90s so I'm quite used to it, so I'd love to know what I've been missing out on.

            • devmor 7 hours ago
              I have a lot of complaints but I would say my three big gripes are:

              - Window navigation within (rather than between) open programs. Mainly if one is on an external monitor, this is just a nightmare and I end up using expose and clicking the window instead.

              - Window positioning (I installed 3rd party software called Rectangle for this last year so it’s kind of solved but if we’re talking about the vanilla experience this is a big one)

              - Having to switch focus to the dock and navigate one by one through shortcuts to open them instead of the Super+Dock position shortcuts that Windows and KDE expose

              • samtheprogram 3 hours ago
                They kinda added window positioning with Tahoe -- there are things I like more about it than Rectangle (resizing), but I found that it was janky enough I switched back to Rectangle.

                I rarely use the Dock, it's somewhat eye candy I leave up, or add stacks for folders that I use, but typically for keyboard action I reach for spotlight (cmd+space). Now, spotlight occasionally shitting the bed, that's another issue...

              • sitharus 3 hours ago
                Interesting, those are problems I don't have, I guess due to my work and workflow.

                Command-` works for window switching as I expect, probably simply due to being used to it so I know exactly how It works.

                Window positioning is an interesting one. I can't stand windows being positioned through tools, I stack them like you would with papers and shuffle through so the edge overlap is really important. Probably showing my age there!

                And I never use the dock. Spotlight gets me everything I'd need from there.

    Touch screens are not pleasant for laptops. I prefer not to have them.
    • mrtksn 10 hours ago
      It's actually quite pleasant user experience for scrolling. Some interactions are better with a pointer, others are better with touch.

      You can try it on an iPad with Magic Keyboard attached, it's very good to be able to do precision through the trackpad and then casually move large things on the screen with your fingers.

      • prmoustache 9 hours ago
        Honestly I just hate having fingerprints on a screen. And I use pageup/pagedown mostly which to me is better than scrolling.

        Trackpad is nice for a device you can lay flat on a table or keep on one hand while sitting on the sofa, not too much when the device has a keyboard permanently attached to it and it cannot fold. I know I have a thinkpad like that and I never use the touchscreen.

            Option-up/option-down?

            Two keys rather than one, but makes up for it by not being way off in some oddball part of the keyboard. You can one-hand it pretty easily, since there's an "option" right next to the arrow keys.

            • MarsIronPI 6 hours ago
              As a stolid classic-era Thinkpad user I don't have a dog in this fight, but it seems to me that the strain of having to hold down another key as I scroll rapidly would get tiring rather quickly. Perhaps if there was a Cmd lock it would be fine.

      • criddell 10 hours ago
        As long as there's a way to maintain the current display density, that would be just fine.

        However, like on Windows, I suspect macOS would increase the tap target size on lots of the touchable elements. Even if I don't use the touchscreen, I would still have to pay the touch target real estate tax in my applications.

        • hntway90904 9 hours ago
          That's a fair ask. My dream would be a simple toggle in something like control center for macOS that can flip between "touch mode" and "desktop mode" with most of the under the hood stuff being the same and just UI changes for the task. No doubt this would create new hurdles for software devs but again I'm dreaming here. Windows 10 actually had this with "tablet mode" in the notification center but I think they already soured people on the touch Windows thing by this point. I think Apple could reasonable do it better if they had the will but they'd much rather you buy and iPad for touch and a mac for desktop and everyone who doesn't want an extra device for certain use cases is left out in the rain.
        • dataflow 9 hours ago
          Note on Windows you can disable the touch device and it goes back to the old density. Don't know if Macs support it.

Using the existing camera hardware + software seems to produce a "good enough" result for most people for casual use. I'm sure with some time and eng, Apple could make the "hack" shippable. But it doesn't earn product managers the big big bonuses, so it'll never happen.

    I always say, people who want a touchscreen on their Laptop never used a really good trackpad. I never missed a touchscreen on my MacBook but when I do something on someone else’s Windows Laptop I often prefer to touch the screen because the trackpad is just terrible.

    Don't love touchscreens that much.

    But I did love my Toshiba Satellite. It was like writing on paper!

    Down with capacitive screens and long live Active Digitizers!

    Using an external webcam is that not more than $1? cool project though; reminds me of how you could use a Wii remote to create a interactive whiteboard.

    It feels real because of the dirty touchscreen.

      I don’t want to encourage people touch my screen and smudge things up.
  • joaohaas 8 hours ago
    As other people mentioned this is obviously not something I would want in my notebook... but I can still appreciate the cool tech!

    I can also definitely see this kind of thing being used in things budget outdoor displays, specially if the UI is made to accommodate the lack of accuracy, and the camera is positioned on the side (since these displays are usually vertical).

      Difficult to capture reflections across a large screen while also dealing with outdoor lighting, glare, and moisture. The touchscreen part isn't usually what makes outdoor signage expensive compared to IP65, temperature control, and a secure housing, all of which would still need to apply here.

      This looks like a neat option for retrofitting, and I suspect it'd work for some non-screen glass applications too. A combined IR/visible light solution would be interesting too, since I suspect those are complimentary (IR touch has issues with radiant light, while this wouldn't; this would have issues with low/no light, while IR wouldn't).

    Is there a coating you can apply to the glass to help with smudge marks?
    • rappatic 10 hours ago
      Oleophobic coating is standard on phones and tablets, which is part of why they don’t pick up fingerprints as easily.

      Some brands offer coating you can DIY yourself (eg ProofTech OLEOPEL) but these seem mostly designed for phone screens. I don’t know whether they’d be as effective on laptop screens

        And this is why modern screens (and eyeglasses) should be cleaned with a damp microfiber cloth and no aggressive cleaners. These coatings are fragile.

        I do carefully clean the nosepads with soapy water, however.

    I think I could do this for less than 15 cents: four small peices of double sided tape, and the tiny mirror, and two hair pins... but the software? Priceless.

    The reason we buy macbooks is because they aren't touchscreens.
  • egypturnash 10 hours ago
    I wonder how well this would work with my bright blue fingernails that are about .5" longer than my finger.

    I then wonder how much recalibration I would have to do when one of them broke and I was poking directly at the screen.

      You could still use the keyboard and track pad
    • jojobas 7 hours ago
      You chose to suffer not just with touchscreens. That said, it would probably work just fine.
      • egypturnash 5 hours ago
        It's honestly kind of amazing how many things seem to never be tested by anyone with long fingernails. My favorite was the time I picked up a video game controller and physically could not use it because the buttons were in a stylish little recess that meant my thumbnail would have to pass through the plastic housing before I could get the button to make contact.

    Checking this profile of a random hacker in 2018, of course they are now working on AI.

      I was working on AI in 2018 too :)

      At that time, I was quite interested in adversarial examples and ML security.

    Neeeeveeeer!!! please let macbooks be as they are .. why would I ever choose to put fingers on that beautful screen ... I don't get it!

      > why would I ever choose to put fingers on that beautful screen ... I don't get it!

      I'm not sure, but bare in mind that the iPad is almost as large of a market as the Mac at this point, and the iPhone has long surpassed Mac revenue. Touching your computer is a very popular sentiment among the grimy-handed public.

      • platevoltage 7 hours ago
        There is a reason why the MacBook hasn't been replaced by an iPad with a keyboard and trackpad attached to it. Very different use case.
        • hoherd 6 hours ago
          You're right. Those are completely separate millions of dollars to be made. Best not let them overlap at all, even if some of us intuitively touch our laptop screens to scroll a window now and then, especially when carrying it around.
        • bigyabai 4 hours ago
          What is that reason? Clearly Apple can put desktop chips in the iPad, their desktop apps already support ARM, and the iPad hardware can absolutely run macOS. What is the advantage of iPadOS, instantially?
  • als0 10 hours ago
    Still an amazing hack today and I love it. However, I heard Apple are developing a touch screen MacBook this year, and I simply don't get why they're doing that. I don't know what's worse, the ergonomics or the fingerprints.
    • bardackx 10 hours ago
      i used to have a bad touch screen laptop like 7 years ago and back then it made the mobile development more pleasant (both native and web based)
    • Etheryte 10 hours ago
      So you mean they're developing the iPad, an insanely popular device, and you're not sure why they would make such a device?
      • nsxwolf 10 hours ago
        I have been around touch screen Windows laptops for I don’t know how many years now, and I have never felt even the slightest compulsion to touch the screen.
        • bigfishrunning 10 hours ago
          It might be a generational thing; my kids get touchscreen laptops from their school, and they interact with them almost exclusively by touching the screen. I agree, I'd much rather use a mouse (or even better, a trackball; i wish most laptops still had those)
