Love mine, but with that said I'll try to answer your question. I typicall use mine 2 spots down from max brightness. I think its very easy on the eyes and easy to read.
The anti-glare coating can make certain 'areas' of the screen look darker then the others. For example, if you are not looking straight on at the screen, one side may look darker then the other. But from straight on, the entire screen looks perfectly even lit.
Also, sometimes on pure white backgrounds etc, you can see a little shading in the corners. However, once you are doing anything normal on the computer - you cant even notice. When my 9200 boots up, I can notice a little fade in the lower corners, but once in windows I cant even see it.
Hope that makes sense! I'm 100% satisfied w/ the 9200, an amazing notebook
