While the keyboard layout seems like something that is (or should be) set in stone, Guru'board'sMiniguru is trying to shake the keys up a bit.
I'm all for anyone trying to improve upon previous technologies, but typing is something that is so natural to me at this point that changing functions and placements makes me nervous. (At least on U.S. keyboards; it took me a long time to become fluent on a French one.)
But maybe the Miniguru deserves a chance. This keyboard's goal is to keep the user's fingers on home row as often as possible, which is supposed to make typing quicker and more efficient.
With a trackpoint in the middle of the board, there are essentially three layers of functions on these keys. For example, when holding down the modifier key to flip the functions, the J, K, L and ; also turn into left arrow, down arrow, right arrow and PgDn.
Users also have the ability to modify certain keys, change functions around and then save alterations to the keyboard's firmware.
I don't know if I'd want one, but maybe its one of those gadgets that's just crazy enough that it could change everything.
