> The stopwatch consistently proves mousing is faster than keyboarding

Without specifying how it was tested that's meaningless. For example I've read of a test where keyboard users were slower because they had to do a find/replace operation on a file manually, moving the cursor only with arrow keys. That's like saying using the mouse is slower after forcing mouse users to type text on a virtual keyboard.

I think in most scenarios both can be fast enough that the difference doesn't matter, provided there's proper support for both.
