I got a Nexus One. Glad to get off the BB. I didn't have battery problems, but their bluetooth is terrible. Especially when paired with a plantronics headset. I have 3 headsets. Bought about 1 per year and finally just gave up and went wired. Which I like for the lower radiation anyway. I do wired everything, even home network. The only wireless I give up and completely accept is a cordless phone. (I know wifi and bluetooth are basically the same here)
My black berry lived at least a month after going through the washing machine so I respect them for that.
I agree that if the signal is lost the BB will search your battery away.
