Like... really F***ing long!
I have a 6Gen 80GB iPod and it acts like how a Windows 98 on crack would after a curious little 12 year old boy who just did his first porn search that lasted 3 hours, especially when I try to sync it.
Well... depending on how much music I'm putting on that wasn't there before.
If I sync all my music and it has nothing on it, it then takes about... hmmm... I have never tried that but I think it will take a really long time considering I have 60GB of music.
BUT I JUST PLUGGED IT IN AND IT WON'T EVEN SHOW UP IN iTUNES, AND IT'S BEEN PLUGGED IN FOR LIKE 30 MINUTES!
Ugh, >.<
