No discussion about ergonomics is complete without a mention of the Svalboard[0], a spiritual successor to the DataHand you can actually purchase today. I'm not affiliated in any way, just a happy user who's career has been saved by the Svalboard when no other ergonomic keyboard could.

Old school datahand user here, are you using the trackball version of The Svalboard? How does it work as a mouse replacement?

Currently using a Magic Trackpad, but might upgrade to a trackball for convenience. It's supposedly on par with standalone trackballs!
