even when the mouse is next to the keyboard. Imagine entering values into a spreadsheet without being able to use tab or enter. How annoying is to have to lift your hand up move it 6" to the mouse, and then move the mouse a 1/2 inch and then return your hand to the keyboard and find your place on it again. It gets old around the 5th time you do that.
Anyways, just agreeing with you for the most part.
