The MiniGuru keyboard has three layers of functions designed to keep your fingers on the home row. Theoretically, that means you could type more efficiently. It would also mean a major overhaul to your typing technique.
Special modifier keys can be held down with a free thumb, allowing the user to cycle through layers of programmable key functionality. For example: hold down the modifier and J, K, L and ; can become arrow keys. There is also a mouse pointer in the centre of the board if you choose to take this whole home key thing to the limit.
Again, the options for the keyboard are highly customisable, with changes saving to the firmware - but it's going to take a lot of convincing when this thing comes out at the end of the year. I'm set in my typing ways dammit. Don't try and change me. [Guru Board via ZDNet]
