That all sounds great and I would certainly try those if/when I get a unit, but I would want a program that is native to the unit with maps on the sd card and not have to require internet access.

The real appeal to me with these units is if I can have a web browser and VNC veiwer and add a full GPS application. Then I could dump my stand alone GPS unit. But it doesn't seem like that is really supported yet, nor do I know if that is even a reasonable expectation.
