Well, this actually is not about the keyboard being cramped - the keys are literally unresponsive. I'm a hunt-and-peck typist, and I'm talking about hammering a key a dozen times and it still might not respond.

CCCCCCC (7 successes)
MMMMMMMMMMMMMMMMMMMM (20 successes)
(the 7 'Shift-c' successes were scattered; 'Shift-m' typing gave irregular (delayed) key-press indications, but all twenty hits displayed)
Recently the TP was near-freezing, and I determined:
the 'c' key depresses only if you hit it along it's left edge;
the 'r' (and to lesser extent the 'f') keys reliably depress only if you hit them on their right half;
'Shift-c' (and to a lesser extent 'Shift-v' and Shift-b') rarely depress at all, while 'Shift-r' and 'Shift-f' work fine;
the 'Ctrl-' version of the 'c', 'v', 'b', 'r, and 'f' keys all depress normally (although only the 'c' does anything);
the right arrow key is most often frozen, but this can change quickly - sometimes the right key works fine,
but then the up or down arrow is usually frozen instead;
most other keys work normally.
I should mention that my TP screen is protected not only by a thin screen film, but also by the thicker carrier
film that you're supposed to remove, but I don't know why this would cause the anomalies, since most keys work fine.
Shift-c is the most consistently stubborn key I notice, even when it's fairly warm. I'm often at 50 or 60 degrees F, and when any of the arrow keys are stuck, it's just too tedious to write much of anything. Sometimes, at warm temps, a completely-frozen arrow key will be freed (at least briefly) by simply turning the TP off and back on. I don't know if this suggests a software problem or a power-distribution problem.
I wonder if this could possibly be a software issue, that could be fixed. Or maybe it has something to do with the graphical key positioning - if you think of the touchscreen as a grid, then maybe most keys are covering 'sweet-spots', but some are over 'four-corner' areas and aren't getting enough 'juice', or whatever; the problem seems concentrated at two places on the keyboard ('rfcvb' and the arrow keys). Maybe it's just 'normal' variation in the touchscreen, but it's irksome.
