I can't get my hands on mine yet, so I have been checking out the videos on you tube. This thing just looks fantastic. One guy was reviewing about all the things you could do with wireless mouse, external hard drive, and usb thumb drive. Of course you need the keyboard for that due to the keyboard has the usb port. Also saw one video somewhere where the guy was using a ps3 controller on one of the games. Transformer is a great name for this tablet, for it truly does morph from one devise, function to another.
