Old thread, but I'll second that it works while browsing the web. In fact, I've had my webcam streaming live video while DeLorme was giving me a nice display of exactly where I was, going down the highway. The one in the 595U is quite accurate. My new phone has a better GPS than my old phone, and it even has the option to enable NMEA output of the GPS over bluetooth OR USB, so I don't even have to run a cord to the laptop for my GPS.

There are some kinks to the 595u's GPS. I have one, and yes it will work with any program that is made for GPS use. However it can tend to give you a delayed signal, and is not very accurate for directional use, at least it never was for me.
