No. Remember that Apple sells devices other than Macs: they were all non-IT people who liked their iPhones and figured they’d try a Mac for their next laptop and liked it. One thing to remember is that Windows is a lot less dominant when you’re looking at what people buy themselves as opposed to what an enterprise IT department picked out. There are a ton of kids who start with ChromeOS or iPads, got a console for gaming, and don’t feel any special attraction to Windows since everything they care about works on both.

> You apparently think it's because "users are just too dumb to buy the good stuff".

Huh? Beyond being insulting, this is simply wrong. My position is that people actually do consider fast, silent, and multi-day battery life as desirable. That’s not the only factor in a buying decision, of course, but it seems really weird not to acknowledge it after the entire PC industry has spent years in a panic trying to catch up.
