I use a Dell Axim X50v and a BT-338 bluetooth GPS receiver when I travel, which is usually everywhere. Software is iGuidance 3. Ohio to Colorado and everything in between, Ohio to New Orleans to Virginia and back. The combo works amazingly, and when you're going to be out of the car you can just take the pocket PC with you, which is good for security as well as for all the benefits that come with having a pocket PC (jotting down notes, tasks, calendar, etc). It's a great way to multitask with your pocket PC. It's great having a totally portable GPS system because you don't have to be in the car to use the GPS. I've used my pocket PC and GPS receiver to walk around cities and find restaurants and stuff. I've used it to figure out where I am while out backpacking.
