Have you ever thought about how you might improve the standard QWERTY keyboard? Jesse Vincent has. He's a keyboard enthusiast, a rare breed of geek inexplicably obsessed with text entry devices. We found him showing of Keyboardio at TechCrunch Disrupt -- a butterfly-shaped keyboard designed to put more emphasis on the opposable thumb. In addition to general ergonomic tweaks, Vincent's design puts keys like ctrl, delete, shift and alt under the user's left and right thumbs, taking the load of peripheral toggling off of the pinky finger. There's also a new "function" button under the typist's palms, which can apply macros and modifiers to almost any key.
