So can you not use the controller for general gameplat at the same time as using a keyboard just for typing?
Actually, that's the optimal way to play for all three systems. Using the controller to play the game, and the keyboard to type, use or set macros, and such. FFXI, in particular, was made with a controller/keyboard setup in mind and is actually recommended that PC users get a controller for their USB or gameport. It's not particularly mouse-friendly, ingame.
The Xbox 360 uses USB keyboards natively. (You can use it pretty much for any text entry, anywhere, and makes adding custom soundtrack info a snap.) Just about any 360 game with text entry works as well. FFXI also inherits use of the USB keyboard.
