I made an iPad reservation at my local Apple store. It says I can pick up an iPad between 9:00am to 3:00pm. So my question is this: how will they know who I am and that I do have a reservation? I printed the email confirmation but it really doesn't say anything special nor does it have any confirmation numbers. what would keep any Joe Schmoe from sending out these mass emails and having tons of people printing the same confirmations? surely Apple has to have something figured out don't they?
