I used a black AEKII and ADB mouse from my Directors Edition on my G3 tower in preference to the USB keyboard it came with... they really are just such a nicely designed keyboard,. I use the black variant of the extended USB keyboard on my G4 and a puck mouse (I actually like the puck) as it doesnt have an ADB port, which i find all in all to be almost as nice a keyboard to use as the AEKII, tho if anything I'd prefer it to have the extra bit of a lip beneath the bottom row. It's reasonable tho, and far nicer than the early small footprint USB keyboards.
