I worked all over Europe for a bit using a large number of the European variations on qwerty (y and z switched for instance and punctuation in unusual places). I found the constant switching meant I was slower on all keyboards - but maybe it was worse because the keyboards were kind of the same. Maybe it's not such a problem if you switch between, say, qwerty and colemak.
A friend of mine in Canada tried it for a few weeks at work only ("I
figured there was no chance of losing productivity at work") and used
qwerty at home and seemed to do fine with switching. No subtle
differences, it's a whole different mode of typing.

That's distinctly not an advantage for those of us who type numeric
IDs into database driven applications.

He also got me to use a "shaking hands" position mouse. We're kind of switching into public service/health announcement territory here: but if anyone is interested, a good link to buy this sort of stuff is www.ergonomics.co.uk under Products->Accessories. I also use a specialist mouse wrist rest from Fellowes that moves with my wrist.
I'm curious about trackballs. I use one ever since i had a minor
twinge that might have potentially indicated RSI or CTS and I haven't
had a recurrence. They do still require you to twist your arm to use
though (but movement of the hand is distinctly reduced).
