What can a PDA do for me?

I've been to both, but they are both trying to put the best
face on their products. No one says; We don't have any way
to connect to pitot, or TE probes, so the PDA does this or
can't do that. I see combinations of PDAs, varios, flight
computers, GPS units, IGC loggers, etc., but it's hard to
figure out what data they have coming in and what's doing
what.

Anyone else want to comment on the relationship between a
PDA vs a flight computer and what the PDA can do vs. what it
can't and why?
