After 2.0 there seems to be a lot of people that are having problems with the iPod taking a long time to sync because it is being 'backed up'. Can someone explain what exactly it is doing when backing up? I have read that it backs up your stuff to the iPod so it's easier to restore it...uhh, isn't everything already on the iPod in the first place? Otherwise, it seems to be backing up to my computer somewhere. The reason I say this is I watched finder during the backup (iTunes was the only process running), and I went from 11.98GB to 11.43GB on my hard drive (I have almost 13gigs of stuff on my 16GB iPod Touch). As you can see my HDD is getting close to that magic 10GB number, and I don't want unneeded backups hogging the space. So, any explanations or anything? Thanks.
