This seems to depend on the nature of the command --- "move to the word I'm looking at" is often faster with a pointing device (though I haven't regularly used a _mouse_ in years, I use a trackpad on the left and a digitizer tablet on the right). For most other text-related commands one uses often, I'd agree (though I've never used a stopwatch to test it, and "the easiest person to fool" is often one's self in these sorts of "efficiency" contests --- perception can mislead).
