So I go to the Apple Store Glendale today and snag an iPod 20GB. I set it up on my PowerBook and play some music for a little bit, then it starts acting funny. There are numerous problems with the buttons and scroll wheel, and the iPod resets randomly. I take it in, and they do a restore no less than 4 times to no avail. So my new toy had a useful life of less than a couple of hours. Worst part is they sold all of them so I couldn't get another. Got a refund instead. Just wanted to share.
