The Nuvis are nice devices. The battery life is a deal breaker for me for touring though. If I am only going to turn it on once in a while then the utility is not worth the extra weight. In fact GPS technology has not yet really made the cut for me for touring. That is strange since I have embraced the GPS for other functions. I used on on my sailboat when I owned one, I never trail run without my wrist GPS, I typically take a handheld GPS when back packing, and use the Nuvi on car trips. I do have gps capability with my cell phone and it can provide directions where there is a cell signal. I have yet to bother using it on tour though.
