I've done this with every flash media I've owned since the beginning.

I've *definitely* seen glitches in xD with my wife's Fujifilm F31fd.
Unlike
SD, all of the "smarts" have to be in the controller, and I think
there's a
lot more room for errors. Removing card while the filesystem is
mounted can
destroy data -- even if you haven't written anything. So in that
case, I
think the paranoia is justified. But fortunately, not relevant to
Pentax.
As far as I'm aware, SD does not include an in-card controller either.
Only CF does.
Removing a card while a write is in progress will cause problems in
every flash memory card system I've used, no matter whether it's any
particular card format.
That said, I've had no problems with any of them. I stick cards into
compatible cameras and card readers without much expectation of
difficulty, and have not had any problems doing so. I see no reason to
get paranoid about it.
