Got my w500 yesterday and am totally happy! Just have it projecting up on the wall, and it looks great. Because of my limited space it's only a 90" diagonal (max zoom), but it's about as big as i'd like it from where I'm sitting. Don't have my dvd player yet, so I just popped a dvd in my laptop and hooked it up via hdmi and my 5 minute testing session turned into a 2 hour viewing
I didn't see any quirks like SDE of pixelation etc, but I'm not a picky videophile either so that probably doesn't mean much.
I tried taking some photos of the image but they didn't turn out right, I'm not sure what the best way to go about it is.
Anyways, I'm happy. For 799$ it feel like I'm getting great bang for my buck.
