Comment Dvorak (Score 2) 307
I learnt it during a summer internship in about a week, and never looked back to qwerty. This is purely a preference, and I heard both positives (speed) and negatives (fingers don't move as much so causes more rep strain injuries). It def improved my overall typing speed, but caused some grief when using CTRL+ZXCV and also in various games with one hand on keyboard (usually switch back to qwerty for them). You won't have as much problem switching because you already got the motorics skills down, just need to have the new layout in your head. Btw, switching back and forth between layouts takes about a few seconds for my head.
