As much as I didn't want this branch of the discussion to occur, I
must make a single comment to it. Regarding the physics you mention:
you say that a large (presumably massive) object cannot be accelerated
quicker than a smaller object. That is true given a consistant force
applied against them. However, if the force being applied to the
larger object is larger than f*M/m than it will in fact accelerate
quicker. In that respect, I dare suggest that the arm muscles (vs. the
finger musles and respective masses) meet this requirement. Maybe an
anatomy specialist could correct me?

Unless they've got a T9 dictionary and only ten keys! I once dated a
girl who out-typed me on her Nokia mobile phone vs. me on my A4
wireless keyboard.

That's allright for me, Gmail breaks threads on subject. Most of the
time it's a pain (and there's no manual override) but for once it
works to my benefit.
