Has anyone been using a PDA with SatNav and made use of the PocketGPS free Camera positions database?

I've not read fully through it, but it seems like an ideal way to get the most functionality for the least dosh. You get a PDA with GPS and Sat-Nav software, then download their free DB of camera positions [img]/ubbthreads/images/graemlins/smile.gif[/img]

Being free I guess it's not going to cover roadworks cameras and other temporaries that Road Angel (+ others) might.

The PocketGPS site is pretty good and has lots of reviews of various products, including GPS camera systems.
