Typing and playing the piano require the same level of hand eye coordination. Interestingly, the keyboard is set up so that your left hand does most of the typing. Most of the finger work on a guitar involves using the left hand. Music is a right brain activity. But left handed people tend to reverse the guitar so that they use their right hand more.
Just thinking out loud. :-)
When I played the drums I was left handed. That is to say rather then having my right hand holding a drum stick and my high hat to left I held one of the sticks in my left hand with my high hat to the right.
