Well if we're trading anecdotes, my sister-in-law (a serious geek type herself) wanted a MacBook and I convinced her to get a Windows PC instead. And of the several computing devices in my house, Apple products outnumber those running Windows 2:1.

The difference is, I bought my Apple devices for dirt cheap from my previous employer, whereas she'd be buying one retail. Spending 2x the money for the same hardware capability and an OS that's equivalent does not make economic sense to me.
