I've been using my 200LX with a Nokia PC Card for a few weeks now.
I use it for mail (using the built-in CC:Mail), for Compuserve
(using TAPCIS in DOS; although I've just ordered acCIS) and for terminal
access to Unix machines.
I've never expected the batteries to last for more than a day under
frequent use in this manner, but normally the do last for two days of
normal use. Obviously, I avoid using it with the card inserted if I don't
have to (the card seems to draw power when it is in the slot regardless
of whether it's being used or not) but at times I have been forced
to 15-25 minute terminal sessions and have been able to continue using
the machine in the normal manner for the rest of the day.
It does drain the batteries, of course, but not unacceptably.
I'm using NiMH:s at the moment, using an external (slow) charger.
I have two pairs of batteries and charge the one I'm not using during
the day. I always carry a pair of Lithium AA:s with me for backup.
