Whats a good (inexpensive keyboard) cover that sits flush like the image above? I've been using a iSkin Classic for a while and it sits above and over the edge. And along with my RadTech ScreenSaverz really puts a lot of physical material between the keyboard and screen. I'm beginning to believe that the large amount of material is damaging my screen. Therefore, I would like a new keyboard cover that sits a low as possible.
