I got the new 40 gig ipod today. This is my first ipod, and wanted to ask about a couple things. First, if I skip a few songs, I can hear the hard drive whirring up. It's audible, but I wouldn't call it whisper quiet. Is this normal or is my ipod unusually noisy? Second, I was thinking of installing Panther on it (why not?) and it wouldn't install. I guess it's because ibook software only installs on ibooks and not ipods? Any info on these two things would be appreciated. Thanks.
