After going through countless numbers of warranty swaps for various problems -- with backlight bleed and dust under the screen being the two main ones -- I finally managed to get one that's pretty much perfect. There's almost no backlight bleed, and there's ZERO dust particles under the screen. The only real thing I noticed is the slightly uneven backlight along the left edge of the screen. But honestly, it's so subtle, I think I can learn to live with it. For those who are sticklers about these sorts of things like I am, don't give up. You will eventually find one. And it *will* be worth it. Feel free to tell your experiences with this sort of thing, too. I'd love to hear them.
