This question could technically go on meta, but I think it makes more sense here on AskDifferent proper. So the new iPad contest was awesome. I even won something.
Here's the question: When I go to an Apple Store for a Genius Bar appointment, they often will look up the device's serial number and match it to my Apple account. Since the prizes were purchased by a StackExchange employee, ware the devices attached to his or her Apple ID? Can I go to an Apple store and add AppleCare, or do I need to transfer ownership, or are the devices registered to the winners individually by virtue of the fact that it was shipped as a gift, with a gift message?
