Just on the topic of using a keyboard for chat on the PS3:

Is it possible to use mouse, keyboard, and gamepad at the same time on PS3? E.g. keyboard for chat, pad for general gameplay, and mouse for manipulating the UI? I'm guessing this is how pad users on the PC operate. The biggest issue with the PS3 (IMHO) is selecting the chat box in the first place.

Sorry for hijacking the thread
