This is a very Ford vs. Chevy kind of thing. I am a declared Canon fanboy. I love my 40D. When it comes to the magazines and expert opinions about image quality and all the fine little points of that I think that for the vast majority of people, those differences are negligible. They really get very nit picky about it and it's easy to get caught up in the minutia of the comparos. Granted, to some people that stuff is critical but not for most.

Personally, I prefer the controls, ergonomics, and the overall system that Canon presents. The Nikon dSLR's I have handled, and I will admit it's limited, I have not liked the controls and the feel was not as substantial or comfortable as the Canon. That might be because I was not looking the Nikon D300 which I think is quite different that the typical D60's and D90's. I have played with a D3 a bit and that is just a different league in every respect.

I would say that one of the selling points of the D90 is the HD video capability but from what I have read, it's really very limited especially when compared to the Canon 5D Mk II. Price wise it's a big difference but I just wanted to point out the limitations with the Nikon.
