If you find the white keyboard a little boring, there is something you can do: get yourself a keyboard from a PowerBook Pismo. The bronze keyboard of the Clamshell's elder brother has exactly the same mechanical layout, only the connecting cable is different. For a switch you only have to remove the keycaps with leaving the mounting brackets in place. The keycaps of the PowerBook Lombard may work also, but i havn't got one of these, so you have to try yourself.

My tool for removing the keycaps is a small screwdriver. You can slip under the plastics and lift it carefully. The larger keys like SPACE or RETURN have two mounting brackets instead of one, which takes more time. Replacing the keycap with a new one is easier - simply put it in the right position and push it down.
