Looks like the iPad 2 was in much higher demand that even Apple could have anticipated. Many may remember that iPad 2 units were on backorder soon after launch. According to Fortune, between mid-April and up until July 8th, iPad 2 shipments were backordered 1-2 weeks, and that was direct from Apple.
Shortly after July 8th, it was pushed down to 3-5 business days. That’s not too bad, but it’s still a delay. Today, you can order an iPad 2 direct from Apple and expect a 1-3 day wait time for the order to ship. Remember, that’s to ship. So you are realistically looking at a week to receive your iPad 2. Still, based on personal experience with Apple, they have been great about shipping products as quickly as possible.
