I went to Halcyon,a little coffee shop in Downtown Austin, last week; and it looked like I'd walked into an Apple commercial. I counted three iBooks and four PowerBooks (including my own.) There was one guy there with a Dell, and it was the only PC in the room.
A friend of mine just got a new work laptop. He works at 3M, and they just took away his ThinkPad and issued him a PowerBook. This should be interesting, since he's one of the ones who looked at me a little bit funny when I abandoned Windows for the Mac.
