just another piece of input. I've had both a palm device for a number of years, and now a PPC. Hopefully that allows me a bit less bias...
That being said, I will totally recommend the PPC. I don't know how battery life compares, but with the newer CF gps units, battery life has yet to be an issue for me. The OS itself seems much sleeker, easier, and more functional on the PPC. I think it's mainly because being from Microsoft, it's so similar to Windows itself. I don't consider myself a MS fan, but my personal thought is they've done the ppc correctly. Plus, I have far fewer syncing issues with this than I did with Palm (for better or worse, since it's a MS device, they make sure it syncs, where as they have no reason to make it that easy for palm devices).
OK, now can you tell me everything there is to know about gpx files? I'm a mapopolis user, and this seems like it could be an awesome way to better utilize my time. Give me as much detail as you can on this, please....
Thanks
