I, for one, usually work with one hand on the keyboard and one on the mouse. But I'll tell you why I won't switch from windows to osx or linux until I find a match for one program. Strokeit. If you've used mouse gestures in Opera, you know. To compose a new email? alt+tab (2 points) or click the mail program (since it's always running), and right-mouse-button-drag-down. Done. Is that 2, or 3 total? I count it as 2, one for the click to select and one for the "stroke". To get rid of that new email? One stroke. Open a link in a page riddled with them into a new tab? One stroke. And so on for all of my commonly used things. *That* is the kind of thing that has actually made people ask "what the heck did you just do?"
