Have seen reports that leaving a iPod plugged into the computer can over time cause problems. If that is so, then why doesn't Apple include a AC - USB power adapter w/ the durn thing? Its not like a person will always have a computer nearby them either if they need a charge. Sorry for ranting... just got refurb iPod and learning, and tad disappointed in that aspect of it. Have ordered a power adapter from Amazon - same $ as Apple, but free shipping.
