The Canon XSi looks like a really nice camera. But... the Nikon D5000 seems to be just as good as the Canon, plus it does video.
If you compare side-by-side, you can see the Nikon has a slight edge. The sensor is a bit bigger, it can do ISO 3200, the screen can flip and tilt, and as I mentioned it does video.
My heart is with Canon but the Nikon seems better... for $150 more. What to do???
