I use an integrated laptop/PDA/GPS system everyday in my vehicle as part of work. I also link up to satellite imagery (geotif.) and overlay my electronic maps. I have tried many commercial and home made sysems and can assure you the RAM MOUNT stuff is the best.

Out of interest, my brother is a choper pilot and mounts his PDA on his thigh with a strap. His GPS is plugged in (but mounted elsewhere). He only needs to look down at his thigh to get the info he needs.
