I tried registering mine for AppleCare yesterday and couldn't do so. It kept insisting that I was registering a G5 PowerMac. I called Apple. They also said that, yes, the serial number was that of a G5. Hmmm. Given that the iPod box, the back of the iPod, and the "About" screen all gave the same serial number, I'm guessing that either (a) Apple made a mistake, or (b) the new G5s are a lot smaller than my 'old' dual-2.0. They finally decided that maybe they'd made a mistake, and allowed me to register, then found on another system that the serial number was legitimately an iPod. Imagine my relief! 🙄
