I have been hearing a lot about this GPS or the Global Positioning System. Most of my neighbors and friends have been telling me to also use one. I have been seriously considering buying one but I want to find more about it first and make sure that the money I am going to spend on it is worth it. I hope you guys could give me simple facts about GPS, how you use it on your daily lives, well, basic stuff. I know there are a lot of reviews of various GPS products online but I can no longer differentiate the sales pitches and the real reviews. Thanks for the help!
