The chaps from Gaming Nexus managed to get a hands-on with the QWERTY keyboard add-on for Xbox 360 - the ChatPad, and they seemed suitably impressed with what was still an unfinished product (missing an LED).
Here are some of their thoughts, "The ChatPad snaps snugly onto the bottom of the controller. It's a pretty tight fit so you don't have to worry about accidentally knocking it off during gameplay. The unit isn't really that heavy and doesn't really impact the weight or balance of the Xbox 360 controller. I think this is something that a lot of people will snap on and leave on."
