I won’t buy Apple. I do a ton of video and gif editing, and all of the free software in windows is just too tempting. I also like to save movies in compressed avi format so I can stream them to my modded Xbox in the living room (no digital here). That requires a bunch of software that I am not sure is available on the mac.
I am just too cheap to buy a Mac but I have heard really good things about Ubuntu.
Also I won an Ipod nano at some industry event and I hated the damn thing because I hate iTunes. I just want to drag and drop my damn mp3 files. So I gave the nano to my son. He of course doesn’t mind itunes and uses the hell out of that thing.
