I am selling my new, never used n900. I bought it in January of this year from dell.com; receipt available on request; as an emergency replacement for a failed n810. I have never used it, some of my critical applications never got fully ported and it's just to small for what I need. I took it out of the box, put a screen protector on it and there it sat. I have a custom case from thepouch.com and an 8gb micro sd card that goes with it. I'm going with an Asus T91MT, a little bigger than I'd like, but my stuff works. Steep discount to active Maemo developers.
[edit] I should mention that I paid $523.62 US for it. I'm looking to recoup some but I realize I'm going to take a loss.
