I don't know about the other stuff, but your concern is well placed -
the battery is inadequate.

You need an external source, - either DC from the aircraft, or you can
use an auxiliary battery source.

I figured this, particularly with Bluetooth going. I've been told about
2-2.5 hours before the iPaq is dead. The idea of Bluetooth is to
eliminate all the cables, and I suppose that it's still a win if you can
eliminate the data cables, but then I'll have to figure out a solution
to the requirement to plug in 3 cigarette-lighter cords (1 GPS, 1 XM WX,
1 iPaq).



The screen size is not all that bad, however. The IPAQ screen is
comparable to a Garmin 430 if I am not mistaken.

I think you are right, plus the 4700 screen is a VGA screen from what I
understand -- much superior to the 430. I think that the 4700 screen is
supposed to be decent in sunlight, but I had a few minutes to play with
one recently and I thought that it was almost unusable in direct
sunlight. Not sure if a good Tablet (like the Motion M1400) would be
any better in that regard.


My real debate is whether I stick with the iPaq or go TabletPC, or just
stick with the GPSMAP 195 for now. Approach plates would be more
practical on the Tablet I think, I'm not sure that I could get rid of my
paper if I had to mess with them on the iPaq.
