Maybe a dumb question but I've never had it before... In the lower-right corner of my whitebook, there's a bright white oval of sorts about 1/8" in diameter. It can only be seen when there's a white background (like right now here in the forums). After trying to clean it like it was a smudge , I'm almost certain the pixels are dead in that spot. Given the size of the area, how many dead pixels are we talking about and would Apple replace my screen? It's no big deal really since it's at the bottom but if this thing were in the middle it would be quite annoying.
