Nice Little Touch – iPad Shows Battery Percentage When Placed into

Just a very quickote on a littleicety I'veoticed when putting the iPad onto its Dock. Just as you place it onto the dock, it displays the remaining battery percentage in the middle of the lock screen, just below the battery image.
Here's a great factoid from iFixit's teardown: the iPad power source is made up of two batteries that are each roughly the same size as that found in the iPhone. The kicker Each has 2.5x the capacity. UPDATE.
