I've got a Garmin iQue3600a. It's got all the usual Palm applications as well as a good GPS reciever (WAAS capable, no use in NZ), a Jeppesen Pacific database as standard. You can buy the nautical and road maps etc also. I've also got a 1 Gig SD card with a bunch of MP3's on it. Very good for aviating, probably fine for road/boat too.
