Many are worried that they have not been charged for their Apple Watch yet. If your order is being shipped to Austin or Houston, it is likely that you will not see moment until tomorrow, as there is already a big batch of watches in Texas, and consequently, Apple needs less time to ship those items. This is really just an educated guess - no insider information here. I think it's a very good guess, however, because I know quite a few people in Austin and Houston who ordered right as pre-orders started but have yet to be charged on their cards yet. If your Apple Watch is shipping to Austin or Houston and it has already moved to "preparing for shipment," please reply to this thread with more details!
