A handshake position (thumb up) seems to be the most neutral and strain-free position for my hands. I've been using a handshake-position mouse (3M Ergonomic mouse) for a few years, and feel that it doesn't cause much harm. I'm not certain any computer input device causes no harm, and have recently added left and right handed Evoluent vertical mice
to the mix. I now switch between left and right handed mousing at work and use the 3M at home.
However, my keyboard, a Goldtouch, only goes to about 30 degrees. So, in comparison to the mice, it is essentially flat. This position has been incrementally bothering me more and more.Parts
Goldtouch Keyboard - they seem to run $150 new, so grab one on Ebay. I've bought several, all in great condition and some even new, for $30-$50 each.
