I read a little about it on the TXB forums from someone that used it at E3. The main thing about the controller is it allows you to use the A,B,X,Y buttons withought taking your finger off the of the right thumpad. For example: in Halo with the regular pad, you must take your thumb off of the right stick to jump. With this pad you can jump, reload, change weapons, whatever w/o ever moving your thumb. This will be incredibly useful in counterstrike i believe. If you want to know where the a,b,x,y buttons are located simply pick up a controller S. The buttons are located where your middle finger and ring finger rest on the pad. As for the little screen where the xbox jewel usually is...it allows you to configure the controls any way you like.
