I know there are a bunch of GPS Projects using the extra cpu cycles on the Empeg to port out to a PDA it seem cumbersome and clunkie

GPSapp does not port out to a PDA. It's all self-contained within the empeg. The only external part is the GPS receiver/antenna, which can often be mounted stealth. Mine is buried inside my dashboard and works fine.

Agreed, the empeg screen isn't the best for displaying maps, and the GPSapp software is still a work in progress (especially in terms of getting good map data into it). But if you've already got the empeg, and space is a concern, then it's a great option for doing zero-footprint, low-cost GPS.
