While I wouldn't argue that some people buy Apple machines because they're "stylish", the vast majority of people I know buy them because they are simply more productive using them. My mom and aunts like them because of the iLife apps (iPhoto and iMovie in particular), and me and most of my developer friends like them because of their versatility (what other brand of machine can easily run Mac OS X, Windows, and Linux?).
Not that it really matters, I suppose, but the claims on /. that Apple machines are about style only are getting a bit old by now.
