Query: Very good keyboard

This keyboard is pretty loud, and you might really like that sort of thing if you're looking at this product. It is a Mac OS X product, and the volume and eject buttons work without drivers. An oddity is that the cmd-opt combination doesn't work on one side of the space bar (it might be due to a kernal extension I have). The power button does not power up my Powerbook, but it does bring up the shutdown dialog if the computer is already running.It's a personal choice if you really should get a keyboard like this. I probably would just get a normal keyboard and save money if I were doing it again. Then again, it is nice to have a clicky keyboard, even if it is pretty loud.
