Thanks to everyone who helped! You bring up some very good points that I will have to consider. I feel myself leaning towards the D7000 at the moment, particularly for the "new" factor. I hope to have this camera for quite a few years, and I just feel like in that time, the D7000 will still be a very capable (and reliable - due to the more solid body construction) camera. I know the D90 is an extremely capable camera as well, I just feel like the D7000 will give me more room to grow into the camera.
