How easy is it to view charts, such as TACs, on the ipaq? Have you
used it for approach plates?

I've found that my PDA has a more viewable screen during bright sunlight
situations, but you just don't have the screen real estate that you do with
a laptop. At night, a laptop can actually be too bright though. Garmin
has a 5 Hz model receiver (GPS 18) that would be great on a laptop for
aviation purposes (most GPS receivers are only 1 Hz).
