To make a long story short, Google Maps just left me hanging in Las Vegas as I was rushing to drop off a rental car ... no, I don't think the rental car drop off is an apartment complex NORTH of the airport. I resolved my issue old school style with a paper map and road signs.
Having said that, and having read many mixed reviews of Google Maps, I dug around a little bit and downloaded Copilot, which appears to have dropped $10 in price to $19. Having done that, I am impressed with Copilot and have begun working with it. One quick impression is that it BURNS the battery rapidly unless plugged in. No huge surprise there, but I'm curious about what other users are doing for mapping. I do run a separate Garmin Nuvi most of the time, but it wasn't available in this case, and frankly, I've been toying with replacing it with the phone. Given the experience with Google Maps, I can't begin to trust Google maps to be the replacement.
