Okay, something cool about the keypad: http://blog.us.playstation.com/2008/08/20/live-from-leipzig-north-american-hardware-announcements/
The entire keypad area is the touch pad.
The entire keypad area is the touch pad.
The Wireless Keypad snaps onto the top of a SIXAXIS or DUALSHOCK 3 wireless controller and comes with some cool features, including a mode that turns the main key area into a touch pad (similar to a touch pad on a Laptop computer). Once in this mode, you can slide your finger on this area to move the cursor on the screen and tap to enter. There will be two short cut buttons on the Keypad that will enable users to jump directly to the XMB’s “Friends” icon and the “Message Box” during gameplay. The Wireless Keypad will launch in late November.
