Sometimes I feel like I'm the only person who can't type on this kind of keyboard because I often use my left hand to type some right side keys and my right hand to type some left side keys. I'd constantly be clicking off into the air on this thing.
I can type near 150wpm, but it is a completely random style that mostly only follows using whatever finger happens to be closest to the next key regardless of which hand it is after leaving every finger wherever it was last used.
