From what I've read about OLED, its main advantage over current LCD
technology is that it does *not* need to be back lit (and thus consumes
*less* power than LCD) and is even easily viewable in daylight.

Of course OLED technology will more expensive at first, but it is
supposed to actually lower the overall costs of LCD applications

Nobody constitutes a pretty big sample.

Musicians are often proficient in multiple instruments with wildly
different key/string configurations. Why should this be any different?
In any case, I believe muscle memory is a non-factor in typing. In fact,
I don't think muscle memory is even applicable to typing.
If you are referring to this,
then I think you are overstating its importance in touch typing. With
the fingers of most touch typists resting on the keyboard,
proprioception doesn't really come into play. Touch typing is not like
the way a pianist uses a keyboard, where the musician's perceptual
system (including arm and hand muscles) "knows" where specific keys are
on the keyboard even though he is neither resting his hands on the
keyboard nor looking at it.
Muscle memory may be a minor factor in the case is which a touch typist
can lay their hands on the keyboard at the proper position without
looking (although usually still requiring the presence of the Home Key
tits to verify that the position is indeed correct).

You imply that few people are multi-lingual. That's more of an
Americanism than a truism.

Duh. It's called Economics of Scale.

And if they had showed a PeeCee keyboard, someone might have said "I do
love their PC-centrism".
