You really really don't have to buy from Apple if you don't want to. I'm considering a surfacebook for my next laptop, and the Surface Studio would be a really cool (but expensive) way of replacing my iMac. Apple doesn't have a monopoly on computers, if they work for you great! If not, there is plenty of competition.

They do seem to still have a monopoly on decent track pads, perhaps we should get the FTC and DOJ involved :).
