It's an ergonomic keyboard-mouse all-in-one!

aptly named KeyMouse is a split keyboard that fits your hands perfectly. Move around the two keyboard halves, and it becomes a mouse.

The KeyMouse folks thought of everything. It has a mouse button at your thumbs. There's a NumLock button on the left that lets you convert the letters to numbers on the right hand. There are a bunch of programmable buttons that pretty much do whatever you want them to do.

You pretty much never have to lift your fingers off the home keys using KeyMouse. But using it was a little tricky. The keys aren't exactly where you'd expect them to be, and my first few attempts at "The quick brown fox jumps over the lazy dog" came back a bit garbled.

KeyMouse founder Heber Allred said it takes about a week to get used to the $399 keyboard. But once you do, your typing speed improves dramatically.
