This has been an interesting discussion! I've been thinking about getting an iPhone, so there's been some good information here, pro and con. However, i never intended for the iPhone to replace my good old eTrex Vista C for geocaching. I am more interested in using it for online information about any nearby caches as well as the other features and applications.
