My N900 is still my daily driver phone. I can still make/receive calls/sms on it, connect to 3G data, access enough of the Internet (Google search, public transit journey planning, Nokia Maps being the main ones) and play some nice games on it. And I intend to continue to use it as my daily driver until A.It dies or has a hardware failure (e.g. charge port ceases to work), B.It stops working with my carrier or otherwise becomes unusable for the things I need to do with it (or I end up in a position where I need to do things on it that I am unable to do) or C.I find a device that is better (and no I don't mean something from crApple or Samsung or Google or whoever that is running all sorts of code underneath that I have no ability to control or change) that I can justify buying.
