With the (hopefully) impending release of the iPad3, I've broken down and decided to get a tablet. I recall reading that previous models sold out very quickly. What advice do you have for someone who doesn't want to camp out in front of an Apple store? From people's past experiences, will I be able to order it online without waiting months? Should I try to order it the moment it becomes available online? How long until stock is predicted to be easily available in the Apple store? Thanks.
