Query: be careful what you wish for...

I thought that the shuffle would be perfect for me. Load it up, and I have enough music to get through the 6 hour drive to my parents' house. A no-brainer for my wish list, really. I was even willing to drop some cash to get a battery pack, dock and other goodies to make my shuffle even handier. Alas, having spent twice as much as my Mom paid for the shuffle and almost as many hours as it takes to get to her house trying to get the &%$# thing to work, and then being unable to get the repair request to go through on the apple.com website, my post-Christmas euphoria has been destroyed.
