All you lucky buggers that have N900 devices - could you please indicate what kind of device/firmware you have (development, pre-release summit etc) along with your typical usage profile and how long your battery lasts?

Are you a 'power user' that lasts from 09:00 to 14:00 before a recharge?

Are you a blogger that can rock online all day 09:00-17:00?

Yes, the 'final firmware' may well change things, but I'd be interested to get an overview of how things stand.
