I was in CompUSA the other day looking for a small keyboard when I saw this:

The keyboard is intended to be used on the PlayStation 2...but since it was USB, I figured I'd give it a try. Well, it works perfectly! It's about the same size as the Zippy keyboards, but no backlit keys. The price wasn't too bad either, only $29. This might be an option if you need a tiny keyboard (and you don't need a backlight or wireless).
