It will be interesting to see how that goes. Most people on Windows don't even know if they have a touch screen or not. Mac users are likely to be more aware, especially on the high end models, but it will be a long time before the average Mac user has a touch screen.
If Apple are going to invest in developing an OLED display for the Mac then incorporating a touch screen into it is a no-brainer that probably won't add a huge amount to the cost (esp. if it shares economies of scale with iPad screens). I don't think its going to be a game changer - but touchscreens are a common feature on PCs with retina-class displays so at the absolute minimum it will help on comparison charts...
Adding multi-touch support to MacOS will improve compatibility with iPad apps (which is currently an under-used feature) and make it easier to use an iPad as a second display - something that is more likely to make me buy a new iPad than a MacBook Ultra, but Apple still wins.
MacOS can't become "touch first" until/unless Apple designs some sort of convertible device & a touchscreen studio display (ideally with 'easel' mode) because Jobs wasn't wrong about the "gorilla arms" effect. There's still a handful of applications where it occasionally makes sense to reach out and touch the screen (mixers and virtual instruments in Logic etc. spring to mind).
In the 1990s, when Apple was months away from bankruptcy, [edit: my emphasis] Apple had a byzantine array of products at every level so complex that Steve Jobs nor anyone else could make heads or tails out of it.
...now Apple are a trillion (ish) dollar company and can afford a more extensive range. Plus, the market has changed with the laptop sector largely taking over mass-market sales and several new product categories emerging industry-wide (like: ultrabooks, netbook/chromebook, ultra-portable workstations, small form-factor desktops and all-in-ones). Come to think of it, most of those "new categories" have Jobs' sticky fingermarks all over them!
Then Jobs whittled it down to high-end laptop, high-end desktop, average laptop, average desktop.
...and portable music player. Wait, what!? Whittling down the inventory gave Apple a few more years of life. Ignoring "back to basics" and going off on a total tangent with the iPod made Apple a massive global brand name... Rules are there to make you think before breaking them.
Who does Apple think is buying this in the current technology economy? The 16" MacBook Pro already now starts at $3,000. What will the MacBook Ultra start at, $4,000?
The sad truth is that not everybody is suffering under the current economy and there are still customers out there with $4000 to spend - and something "new" like the rumoured "ultra" might be more inclined to open wallets than a spec bumped MBP. Prices have gone up across the entire industry which is suddenly encountering
inflation for the first time in its history - and Apple's recent percentage rises haven't so far been as large as some other products. A year or two down the line - maybe the AI datacentre boom will have peaked out and prices fallen back, or maybe people will just get acclimatised to the new prices & inflation. Meanwhile, Apple
have released the Neo to address the tight-budget end of the market.
Also... remember the original MacBook Air, which was
very expensive for those specs, but after a couple of years had evolved into the entry-level replacement for the MacBook. Or the 2012 Retina MBPs which were a substantial price hike from their predecessors (which actually got a spec bump and remained on sale for a year or more).
Ridiculous. Why not just put the camera in a bezel?
Does that mean making the bezel bigger or the screen smaller? Macbooks, iPads etc. seem to have quirky screen resolutions/aspect ratios (rather than industry standard UHD etc.) so it's moot whether you'd be losing or gaining pixels c.f. some hypothetical notch-free screen.
Glass half empty: "notch" (a bite out of your 4k full-screen)
Glass half full: "ears" (useful extra space for clocks, battery indicators etc.)
I mean, I'd prefer a pop-up camera so you could
know it was off for real.
