anything that's a half decent music player won't be an issue in voice conversations
True, but only if the words come through. My old phone (a Motorola, FWIW), picked up every word. With my new one, it sounds to me like the reception is fuzzy. The phone's sound quality is good, I can hear every crackle and pop, and about every other word. I think it's antenna problems, or something.

That still kind of misses the point I was trying to make (whine about). Phone reviews seem to be all about the neat apps, not about whether or not you can hold a conversation. I take my phone to some fairly iffy places, reception-wise, and would like to know if it has the antenna power for me to, you know, use the thing as a phone. /rant

As far as using a Droid as a GPS, the review I read talked about it having a special docking port to put on the car's dash, which would presumably take care of the battery issue. This struck a cord, as DH's Garmin has this cute little habit of running out of battery about halfway through rides and car trips to see relatives.

For myself, I'd probably use the GPS function only when needed, like trying to navigate in an unfamiliar town. I hope I have enough confidence in my navigational abilities to make it down a long straight road all by myself.
