Spherical Keyboards?
Jesse Middleton asks: "I was wondering if anyone knew of an ergonomic keyboard that is a ball shape? Someone told me about it, but I can't seem to find it. I would really be interested in it. In otherwords, it is shaped like a ball and you sit it on your desk and elevate your hands and type sideways. Any help would be appreciated!"
It seems to my that your arms would get very tired if you used one of these for a long time, considering there is essentially nothing to rest your arms upon. Holding arms in the air for a few hours while manipulating fingers at >60WPM would get very old very fast.
