I've been thinking about buying a portable GPS kit (they install on a pocket PC). It seems more practical than installing one in my car for twice the price, especially since I can share it with someone else. Now, first I have to get a pocket PC. I've been told the ideal one is the CompactFlash GPS Kit. So that would mean getting the iPAQ Pocket PC. Unfortunately, I have no reference point when it comes to portable PCs in terms of quality and what to expect. Any advice will be greatly appreciated.
