Did you wait too long to pull the trigger on a pre-order for Apple's newest iPad? Well, it looks like you'll have to join the rest of the US-based iStragglers and settle for a later ship date.

While this is by no means an indication that the company's sold out of its third-generation tablet wares, consider it a last call for the early adopter train.
