The SIIG MiniTouch KB1948 is a small footprint, space saver type keyboard, similar to the happy hacking keyboard. It is about 12 inches wide and 6 inches deep, with full-size keys and reasonably long key travel. On the down side, it has very little row curvature, with the top row less than .1 inches above the middle row.
The keyboard has 81 keys, but is 101/102 key compatible, and uses a standard ps/2 connector. It also has some type of mechanical keyswitches which make nice clicking sounds and give the keys a springy feel. Definitely worth looking into if you are in need for a small footprint keyboard.
