At TC I think you should get one,I just bought it one brand new today...I was like you lurking on this forum since the end of n810 and my wish to get a n900 never fade away since today.
I'm planning to use it as normal phone and developing also,get some skill and experience so I can work with this community for greater apps and stuff
I dont mind the ageing of the hardware as long as you are happy with it then it should be all right
