Personally I think it's beautiful and with the Toshiba hard-drive it seems to perform great. That said, I really don't have another one loaded with Samsung to compare it with. But paying all the money I did for this thing and reading all the FUD (Fear Uncertainty and Doubt) on this forum is no fun.
I feel the same way, you spend the money and don't want to feel like your getting a lesser machine. Until seeing this forum I wouldn't have thought much of it. I do notice when using the computer though that I do end up with a minor headache when using it and staring at the screen that seems to happen a lot. I noticed that even before the Macrumors posts about the displays. It makes me wonder if both panels would do this, if it's the panel, a defect, etc. I notice when I go back to my desktop I don't have that problem.
I do recall getting a similar feeling with a high-res Dell laptop I had in the past and eventually I guess I got used to it and it stopped.
