itunes 7 sucks
Do not upgrade from itunes 6 to itunes 7; not even itunes 7.0.1. The machine on which I'm composing this crackplog is used only for email, non-work web-browsing, and playing music; and itunes 7 skips terribly whenever I load a new page in firefox - and this is not an underpowered machine. The 7.0.1 update actually made it worse!.
This is what I get for being a slave to apple's music library management stuff. Sigh.
