Lineups for the iPad 2 once again formed today at stores in New York City and San Francisco, notes Ticonderoga Securities' Brian White. The analyst claims however that in both cities, checks with shops indicated that resupplies were much lower than the quantities originally available on Friday. Apple's flagship San Francisco store is said to have opened an hour early with about 400 people in line, but people towards the end of the line were being told they might come away empty-handed.
