If you have an existing iPad, you may have noticed that the iPad indicates that it doesn't charge when it's plugged into a standard USB port. In reality, it's receiving a low, trickle charge that slowly charges the iPad when the screen's off (but you would have no way of knowing that it's charging).
The specs on the iPad 2 indicate:
Charging via power adapter or USB to computer system.
It doesn't specify high-output USB ports, so does this mean that the new iPad 2 will actually charge on a standard USB port - even when you're using the iPad 2?
