Linux doesn't run the software I need it to run, so it's not fit for my purposes and Windows is someone's idea of a sick joke. I also value aesthetics and UX in a computer, Linux and Windows are actually offensive to me in those two areas.
I don't feel there's an alternative for users like me and Apple know it.
Edit: This news story has annoyed me, I think Apple have crossed the line, but I need to buy a new personal computer in March and a MacBook seems to be my only option.
