We both have dedicated GPS systems on our respective boats. It just occured to me that it would have been nice to be able to have my own "view" on my blackberry when on other people's boats, and it would be nice to have as a backup when on my own boat.

I'm not sure I have enough confidence in the GPS receiver built into the 8800 to use as a primary system. Perhaps that is why no one has stepped forward with Marine Navigation software for the BB. That and you would probably need to have the maps saved to a SD/microSD card (wouldn't want to get just outside cell range and need a map update!). But still, I'd pay good money for navigation with maps.

If he didn't have GPS, I wouldn't be on that boat at any hour, at any speed.
