One of the statements I see a lot is that mouseless, keyboard only HCI is faster. But as far as I know, to the extent that any real studies have been done at all, this assertion is false.
I don't have the references at hand but I think people like Alan Kay and designers at Apple would think it crazy to even suggest that a keyboard only HCI is more efficient.
