Very nice! But a couple of choices you missed...
On the music one... where's techno et al?!?! Don't tell me I'm the only person listening to techno/trance/etc right now..
On the OS one, you probably should have listed *BSD too. Those weirdos using BSD tend to be odd when you leave them out (Yeah, they could always choose "Unix", but if you have an option for Linux....).
