I'm in NYC right now. Got here on Monday, having spent three days in Boston.
I tried everywhere for a 32gb iPad - no joy. I finally spoke to an Apple employee whose parents are from Scotland - and he put me on a reserve list for the Florida Mall Apple Store (that was in Boston on Sunday, still no email, but I arrive in Florida tomorrow).
I also tried the Fifth Ave store - no joy, but they set my wife up with an iTunes account and reserved one for her in Florida too.
The Fifth Ave guy said the wait is about 5-10 days (up until a few weeks ago, it was 3-7 days). He says demand has increased in recent weeks for some reason.
I'm in Florida for 16 days. If I don't get one, I'll wreck the joint before I go home.
