I would love to purchase something like this if it offered programmer centric typing tutorials. I have found that my right hand has drifted over about half of a key to use these characters "[]{}|" and these such as "^&$%" are potentially used to a lesser degree. I've found at times that my typing speed and general typos with these characters have actually limited my programming speed, so if your software had tutorials for these kind of characters i would certainly purchase it. Perhaps it already does?
