Expose properly and you can shoot at ISO 1600 with Noise Ninja applied. See for yourself. I don't have a picture now, but if it's gonna help anyone make the decision, I can try to get one posted tonight.
Another drawback is no zooming during preview. Some found it a disadvantage as they use the zoom to check focus accuracy. Though I found the LCD to be too low res to tell, even for 20D. I don't find the review time too slow, as compared to 10D and D60. Still usable, if you review. I will try blowing up large poster size after a shoot in June to see the limits of 4mp. Currently, I prefer enlargements of 1D over 20D for 8R and 10R. Personal preference of course.
