yeah it's about 6-8" wider than a standard 104, the flip LCD screen comes close to the bottom of my desk when it's on the drawer.
Underneath it has channels for mouse, headphone, etc cables that are pretty cool I have a G5 mouse and it holds the cable perfectl so I never have chord bind. Well designed and thought out IMO.
Theres just so much more extra stuff than any other keyboard ive ever seen.
