Ok, so GPS can be a little bit confusing, but Pocket PC Thoughts has the first installment of what looks like a three part series about how to get the best GPS system for your Pocket PC. The first part gives an overview of GPS, how it works, the difference between a car’s GPS system and a Pocket PC’s, and error rates. The next installment is supposed to look at which GPS hardware is best, with the following installment looking specifically at the options for mapping software.
