quick update the keyboard i bought (see post 37
) works great.
Just put batteries in, plug in the usb dongle and boot up the PS3 - works first time. lovely keyboard too.
The keyboard has a joystick style mouse controller (like a big 'nipple') on the right, the left & right mouse buttons are on the left - which sounds weird, but is actually very intuative and works well. the keyboard itself is almost full size (less numberpad, and with a smaller return key)
All in all I am very impressed. Just need to get linux installed and start playing with that now!
