the 17" MBP display doesn't seem as bright to me as the 15" but I'm quite happy with that since viewing angles are better and brightness doesn't shift as much. I have a feeling that it's the brightness enhancing filter that makes the 15" so controversial by directing all the brightness toward the middle and front of the display so that any movement of the user to the sides or up/down immediately distorts the image in one way or another. The 17", on the other hand doesn't do that to the same degree. It doesn't hav a great viewing angle, but it's perfectly acceptable in my book. Unlike the 15" I had which I couldn't find a optimum viewing angle when placed on my lap or on a desk near the edge when I was sitting close, the 17 doesn't get in my way, and I'm usually able to view the display at optimum angle, despite the limited hinge tilt. I also just noticed that the 17" display surface feels softer than the 15" more like what I used to see in the powerbooks. When you touch it with little pressure there is immediate distortion, whereas with the 15" you needed more pressure and it seemed harder - the filter? I don't know much about brightness enhancing filters, but judging by the quality of the the two displays and their relative brightness I suspect that the filter is one of the main culprits in producing 'grain' and poor viewing angles. Anybody with more knowledge?
