The lines are forming for the iPad2 (AAPL +1.5%) that goes on sale in stores in about an hour. The consensus is that Apple will sell 600,000 of the tablets in this weekend's debut but estimates range up to 1M, and shipping times shown on the Apple website are stretching fairly aggressively due to strong online demand.
