I'm researching buying a PDA with GPS. I would like it to replace the laptop I lug around on trips I take doing driveaway (mostly delivering new trucks to locations across the US). I would like to have Wi-Fi for email and web browsing, GPS with the right mapping software for trip planning, directions, locations of truckstops, etc. A camera would be nice, but not high priority.
In researching, I've found an overwhelming array of choices, but none seem to have all the right combinations. Many of you have a lot of experiences with using a PDA with GPS for geocaching (which I also enjoy), so what would you recommend if you were starting out with the purchase of a new PDA with attached GPS (I'm leaning toward bluetooth rather than built-in) and the associated mapping software?
Your recommendations appreciated.
