> ...frees your right hand to use keyboard buttons intended for the right hand... On the other hand (ha!) you lose access to navigational keys that are typically used when you're "mousing", changing between apps/tabs and screens - e.g. alt-tab, ESC, alt-w, alt-q, alt-F4, meta-shortcuts, etc. I noticed that I use the right keys - enter, backspace, delete, etc - mostly when I'm typing, so I want my two hands in the keyboard anyway. For me the mouse on the right side is the best combination.
