I bought an n810 towards the end of its life cycle at the beginning of 2009. Then the GPS support was dropped by navicore and flash became outdated then little things... I remember right up until the release of n900 people were saying the n810 would get an update. There was even vids of it running maemo5.

Needless to say despite how awesome an n900 is and how many os' have been ported to it I'm glad I went with an android device.

Got myself a Dell Streak for Christmas and have been impressed by the one man army that is DJ_Steve at XDA. That is the thing about android- there is always someone making cooked roms for your device- even the G1 still has updates, where as Nokia's product support is barely over a year.
