Is the week38 as good as the iPhone with regards to the negative black or "shimmering" issue? I compared my W37 with some display modles at the Apple store, using The Fray music video. While my W37 is better than the W37 at the store, it is not as good as some of the iPhone when it comes to NOT displaying negative blacks. I wonder if it's worth the hassle of swaping for a W38 (no one around here has them in stock) or just stick with my W37? However, if the W38 is going to be as good as the iPhone when it comes to "negative black" then it's worthwhile for me to do the exchange.
