This one looks interesting.<p>I tried the Truly Ergonomic keyboard and while it was innovative, it was hard to get used to the middle row and the build quality was not so good.<p>I ended up buying from WASD Keyboards and I absolutely love their product. Complete customization, a tenkeyless option, excellent build quality, the most durable key caps around, but familiar IBM style key placement.<p><a href="http://www.wasdkeyboards.com/" rel="nofollow">http://www.wasdkeyboards.com/</a><p>This one seems to be something in between these two.<p>In my opinion, the most important ergonomic improvements are to buy a tenkeyless model and set the capslock to a backspace. Having a heavy keyboard with sturdy grips at the base is also important.<p>Exotic features like a split keyboard, matrix layout, and strange thumb controls are just annoying and non-standard. I also somewhat regret having switched to colemak, but not entirely.
