But no, touch screens are what I meant. There's also a scenario where someone is moving away from Mac specifically because they're looking at convertibles like a Surface Book. Maybe before this point they were doing drawing on an iPad, or a wacom tablet. Apple had and still has a huge userbase of artists.

Say that you're one of those artists trying to transition to (opinion me) a superior hardware medium for doing artwork, where you have more control over buying hardware brands you think will be reliable or flexible or portable, and where you can get the advantages of running a full-fledged OS on your tablet. You can buy a PC convertible and install Linux on it. But you won't be happy with how Linux runs on those devices (also opinion me).
