An early estimate on Saturday reveals that Apple may have sold between 600,000 and 700,000 iPads on just its first day. He had originally predicted no more than 300,000 shipped but more than doubled his predictions based on long queues at the 5th Avenue Apple store, where about 730 people lined up before the 9:00AM launch. By comparison, the iPhone 3G lineup peaked at 540 in line, indicating a record turnout.
