I recall beyond the usability issues (who wants a big stupid MP3 player? Not me.), iTunes when you uninstalled it left a bunch of stuff behind on the system. I'm not talking just odd files here and there, I'm talking entire sets of running services you have to remove from ARP or otherwise nuke. Bonjour was one that comes to mind, but there was more I can't recall offhand.
