I use a Palm i705 with the wireless Palm network. I like to use Travel Tracker to keep track of my travel itineraries. It transfers the info to my datebook function. I use AvantGo to get info about the city I'm in. I used to use Vindigo until they started charging money. I use Metro when I'm in cities that have subways and finally, I use Big Clock help me keep track of the time where I am and what time it is at home.

The software is usually purchased at Palm.com or handandgo.com.
