sboisvert, how do you say google further invades your privacy?
I'm interested in hiking and exploring. And I love the *color* satellite images from http://maps.google.com. I'd like to equip my laptop with a GPS unit (maybe a USB device so it could also be used with a PDA) and some satellite-imaged map software. Anybody got any solid, experienced recommendations???
