My Atrix has an 1930mAh battery, I've trimmed down the starting services as well as killed most of the polling widgets. I can go almost a day and a half per charge with wifi, bluetooth and Gmail polling per 30 minutes and really using it, phone calls et al.

To be honest, I find that my experience with Android, all but AMOLED based phones, is better than the N900. I'm a heavy phone user.

Awesome. My personal one was going strong, no drops and no microUSB issues when I sold it. The other two in the office, I can't say the same on the microUSB, one was replaced, the other was just returned.
