I just got my dual 1.25 g4, and the apple keyboard is cool because it has the volume and eject buttons on it. but its difficult for me to type on. will i be able to buy a different keyboard (MS/Logitech) and use its volume/eject buttons if it has it? if not, how would I eject the dvd/cd? It dosnt seem theres a button on the computer itself, and clicking the software's button is not what I want to do.
