BigSmooth, you are vastly overstating the dangers of this technique and may have a misconception about human DNA and the differences and similarities between individuals.

I use "Microsoft Sculpt Ergonomic Desktop (L5V-00001) ". Its pretty great. The battery life is superior to the bluetooth Magic Mosue I use at work (the microsoft stuff doesn't use bluetooth so they must have something lower power than bluetooth?). It is nice having the numpad separate from the keyboard and mouse so that i can position things comfortably.

Wow, i had no idea! Ill stop wasting my time om the foam.

Thanks!
