Sorry if this has been asked before. I plan on getting the Ipad 3 on launch day. I have heard and read on here that when the ipad 2 launched it sold out pretty quickly. Now my hope is to either pre-order and buy at my local apple store but if that does not happen I was wondering will places like Best Buy and Wal-mart (yes Wal-mart lol) have a huge supply? I know no one knows yet but any guesses? Thanks
