I love the display of the GPS on the iPAQ 310. I used it at CES in Las Vegas this year and have had it with me ever since.  Although it requires carrying another device, it has a lot more than most GPS units have.  Here's a quick rundown as to what's on the iPAQ 310 as delivered.

Navigation

• Map
• Go to (choose address, point of interest, Home).  You can also look at Favorites or your History
• Navigational Extras - Trip Planner or Traffic Messages
• Route planning including a log
• Settings (Set visuals, sounds, regional, routes and warnings)

Entertainment

• Videos
• Music
• Games - Gamebox Classics (Snake, Fireball, Jewel Master and Cannons) and Flux Challenge came with it
• Pictures

Contacts

• Keep your contacts and navigate directly to their address with the GPS

Extras

• Calculator
• Clock (including 3 time zones and an alarm)
• Phone

Settings

• Date, Time
• Language
• Media Directions
• Personalization for Settings
• Bluetooth

The screen is clear, bright and very easy to read.  The onscreen keyboard is large and easy to use whether using the included stylus or a finger.  The UI isn't cartoonish, one thing that I've found on some other units.

I like that I can use it as a hands-free answering system when partnered with my Bluetooth phone. This is great when being used in a car as it's safer as well as convenient. 

You can plan your trip online before you leave, then download it to the iPAQ. It's 3-D maps are very easy to read. You can zoom from sky to street level using the wheel on the side of the unit. Use voice or written directions to get you where you're going. Find restaurants and points of interest.

The biggest issue I've seen with this Pocket PC is that it takes its own USB cable to charge via a computer.  I've let it run for hours using the USB I carry for my phone with no increase in battery charge.  It would be much more convenient to have the ability to use any USB cable for charging.

The other issue I've found is that the 'Navigation' button on the keyboard is in the same place and is the same shape as the space bar on a conventional keyboard.  It took me some time to figure out why the machine changed to navigation mode as I was trying to enter a street name with a space in it (Las Vegas Blvd).  Of course, if I'd read the directions instead of diving in, I would have saved some time.
