that explains it.  My hands are larger than most.  On a typical PC 
keyboard, I can hold down the control key with my little finger and hit 
all alphanumeric keys without straining (too much).

never learned that trick.  Even with the old typewriters, I drove the 
key all the way home.  (Are we the only people on this list that 
actually used a manual typewriter complete with carbon paper and whiteout?)

but I do like short stroke because it is less finger movement and 
because the underlayment a laptop keyboard is more flexible than a 
desktop keyboard, I get some bounce which reduces the end of travel shock.

The problem I have with current keyboards is that there is so much 
resistance on the keystroke that you have to force the key all the way 
down until you hit bottom hard.  At least, that's the way it feels to my 
fingers.

yeah, given a choice, I would push most keyboards away.

I might even still have a couple in the basement.  some of the keys 
don't work but they still go clack-clack-clack when you drop them.
