Patrick,

For car navigation, there is good software (with bluetooth GPS) - is
there something similar for aviation?

Yes. Several vendors for PocketPC. One of the most popular in the US is
ControlVision's Anywhere Map. One of the most cost-efficient may be
www.pocketfms.com. If you are from Europe, pocketfms is REALLY
attractive both for flight planning on the PC and the PocketPC and for
moving map display on a PocketPC.

By the way - Pocket Windows exists for several different hardware
brands/cpu


Uh, "Pocket Windows" doesn't exist at all, really. The PocketPC
platform in its current version uses Windows Mobile 2003.
