If you have to look down your dead anyway....... just the programability is nice, and look of it. You can't tell me that it would be cool to hit shift and see all the letters turn to caps on your keyboard, and back into small letters after you let go. Its probably gonna cost like 500+ dollors though, so I'll never buy one.
PS my keyboard is so light that I just pick up and move it over 2 feet so I can use the numberpad and my special right handed mouse. HA
