Great article on different computer keyboards, included are an ergo keyboards, one handed keyboard and some high tech and concept boards. Originally published in PC World, but the CIO link has a better looking slide show.
The keyboard above is described as "Billed as the "World's Best-Selling Vertical Keyboard," the $295 SafeType evidently towers above its competition. My own research corroborates the manufacturer's market-share claim: I couldn't find any other vertical keyboards."
Thanks for supporting Maine VRC.
