do you have any night pictures to show? Mine were really grainy. Your pictures are better then any I got w/ my d40. I might have had a bad one, I also had quite a few other problems with it. the most annoying was that the clock would lose like 10 minutes a day. after a couple weeks the clock was pretty much meaningless. Also, my flash range was completely terrible! I could barely recognize targets that were about 10' from the camera.

compared to the d-40 the i-40 is absolutely incredible. WELL worth the extra $100 in my opinion.
