Seems pretty obvious that some future Macs will have touch screens or larger iPads will run MacOS.
Probably not. Apple has said they've prototyped touch screen Macs and from a UI/UX perspective, it doesn't really work. They've recently downplayed touchscreen Mac talk recently [1].
What Apple has shown is iPadOS becoming more like macOS, supporting a keyboard and a mouse instead of the other way around.
I have a 2-in-1 Surface on loan and it's not particularly good at being a laptop or a tablet because of the design tradeoffs that have to be made. Apple is unlikely to make such a device unless there's some kind of UI/UX breakthrough.
I was really hoping they'd announce a $500 touchscreen lapdock for iPhones with a mounting arm that used MagSafe. Turn iPhones into Macs. It'd be the slickest lapdock I can think of.
I honestly feel like they won't do this for one simple reason: Why sell one devices when you can force consumers to buy two? Apple is keen on somehow making customers buy more things, more accessories, etc. They aren't the biggest company in the world for nothing.
They say it's some fridge and microwave whatever excuse, but the real reason is money. The M1 chip itself lowers their costs by almost $3B.
I’d buy a Surface Studio style iMac in a heartbeat.
