I read, probably not confirmed, that they were holding inventory to refresh so they didn't go weeks after the launch with no product to sell. If this is true, eBay market will be small, only the really uninformed or those who are lazy with a lot of money.
I figure I could probably go back over to that ATT store and pick one up tonight if I really wanted. I really don't want to buy one right now, though, for budgetary reasons. If I go there, I might be too tempted.
