The Europeans have stopped fighting about Galileo , the rival GPS service they are building.They don't want to depend on the American system which could be cut off at the discretion of the Department of Defense. Right now that's the main way we have of getting fairly accurate latitude and longitude, and it's free. Others are using triangulation of mobile phone signals.
I noticed that the number of GPS devices offered this Christmas season had increased over last year, and I succumbed to a deal on woot.com the site that offers one special deal each day. The Navman N40i cost $160 and included AC adaptor, auto charger, mounting device for the car (though California forbids any dash-mounted gear), CDs with other maps, and a small carrying case.
It mainly serves as a touch screen car navigation aid with maps of Canada and the United States already loaded. Voice prompts are in any of eight European languages, and you have your choice of UK, US, or Australian English. However, the inclusion of a 1 megapixel camera was the main attraction for me. The images are stored internally and can serve as destination points or just points of interest. There is an SD card slot (or cable) for moving the images and GPS info to a computer. I'll report back on how much I use it during a trip to Southern California.
