I just got off a chat session with NokiaUSA. They told me the n900 $50 rebate does not apply to the n900 phones they sell and that they charge sales tax to my state (Alabama). I already have a 11/20/2009 pre-order with Amazon for $529. NokiaUSA's lack of rebate and added sales tax makes the Nokia version cost me about $117 more than the Amazon version. So I guess I'm gonna have to wait on Amazon to ship.
