Really? All the emacs users I interact with (including me) are pretty
much completely trained on those keybindings. The arrow keys aren't
anywhere near home row. I certainly can't touch type with them.

Basically, I agree with everything. We've chosen Control for shortcuts
and Alt for accelerators, and changing that would be a bad idea. And
there aren't enough letters to give a dozen of them to movement commands
But couldn't we set up eamcs-like keybindings on Super? Nothing that I
know of is really using that (except Metacity with the mouse, but that
won't conflict), and that gives us a solution much like what OS X does.
Sure, we can't guarantee that keyboards will have a key for Super, and
so we shouldn't use it for shortcuts or accelerators. But these are
non-essential keybindings. If you really want them, you can jolly well
get a keyboard with another modifier key or remap your current keyboard.
FWIW, this is how I have Mathematica set up, and it works well for me.
