I did a little quick look video. This video was done with zero experience using it or any standalone GPS for that matter. I found it pretty simple to set up, but I didn't test it in depth like Jake Richards is as we speak. The reviewer gives the iPAQ 310 pretty bad marks though. I will wait on Jake's to make my final choice.

The review over at I4U is pretty detailed, if you are in the market, check it out.

We had a lot of problems testing the 310 Travel Companion; more problems than we’ve had with any other device in recent memory. This product feels half-baked, is not user friendly, and is frustrating to use, to say the least. We constantly felt like we were fighting the device, rather than having it actually make our lives easier. We do not recommend this product, obviously. If you’re in the market for a full-featured GPS, check out our Garmin nuvi 350 review. It’s the same price and runs circles around the iPAQ in every way possible (except screen sexiness). As a first generation product the HP 310 Travel Companion shows a lot of promise, and we cannot wait for the next iteration once HP has polished the device more.

Pros:
• Gorgeous display
• Games are fun
• Lots of features

Cons:
• Navigation is non-intuitive
• Instructions are lacking
• Trip planner is just a novelty
• Loading media onto the device is confusing
