I've been using the Brydge+ keyboard attached to my IPAD3 for several days now and enjoy it much more than I thought I would. The keyboard clamps onto the IPAD and converts it into a notebook form of computer. The + version includes higher quality speakers. The keyboard and speakers communicate with the IPAD through the Bluetooth protocol. The Brydge works only with IPADs 2, 3, and 4.
