Apple's world-class design extends to the iPad2's cover, which Apple calls a "smart cover." It wakes up the iPad from sleep when you open the cover. It uses magnets, to grasp and auto-align. It also has a micro-fiber lining that cleans the device. Of course, we’ve been seeing many more cases that include Bluetooth keyboards built in, and that isn't covered here. But Apple showed a video of the cover, and it is really, really nifty. Polyurethane for $39 and leather for $69.
