Scott Adams (who lives in San Francisco) got rid of his iPhone because it got worthless reception and he went to Android:

Anyway, my Android phone works most of the time for voice calls. But I’m afraid to actually use it because the battery life is about an hour and it’s no good to me with no power.

Now I only think of my phone as an emergency device, like my first brick-sized cell phone. I wouldn’t use it to make a social phone call. My battery wouldn’t last. And I wouldn’t often use it for email because the keyboard sucks and the battery drains then as well.
