Personal digital assistants (PDAs), such as a Pocket PC or Palm, are a popular way of accessing GPS information. The PDA processes satellite data from a GPS receiver and then displays your current location in a mapping program.
You can use many different types of GPS receivers with PDAs, including handheld, mouse, wireless, and card. This chapter helps you navigate through the PDA/GPS maze by reviewing the different hardware and software options and comparing common, handheld GPS receivers with PDAs that use GPS. I start things off by discussing some of the advantages and disadvantages of PDA-based navigation systems. You might wonder why anyone would you want to use a PDA instead of a handheld, consumer GPS receiver. That’s a very good question; you gadget junkies out there who have your hands raised and are answering, “Because it’s cool,” please put your hands down and continue reading. You’ll find compelling advantages and disadvantages to using a PDA with GPS that are based on your intended use and needs. To see whether you should even be considering a PDA navigation system, review some of the pros and cons right from the start.
