Yes, iTunes 7 seems to be a great program, but I could have skipped it for 7.1. Anyway, Ever since iTunes was upgraded the battery has been run down almost in half the time in playing iTunes 7.0. I mean, Abnormally fast and across three individual batteries. Of course it doesn't seem to matter if it's plugged in, but the fan will kick on eventually if left playing for a while now. Activity monitor isn't finding anything unusual. Specs: iBook G4 1.33Ghz 12" Last Gen Anyone else noticing similar problems?
