Not sure what you’re talking about, a whole lot of people use MacBooks, I don’t think their market share dropped significantly. Desktop Macs, sure maybe but I think even that won’t completely die out.
I’m not sure if that’ll happen any time soon, they’d lose out on the IT professionals, audio professionals etc.
I got one just this year and it certainly doesn’t feel like an iPad at all.
You got a desktop or MacBook? Macbook pro is pretty nice but i dont see a future for osx or desktop. And while i agree some real professionals might keep using it for another decade but the vast majority of Adobe professionals will be replaced by other tech like AI or nuke artists etc
