I had Best Buy gift certificates so I could not resist the temptation. What a difference from last year's model! I'm actually a bit shocked. It's that obvious! My old PW suffered from color blobs, newsink smudges, severe light shadows, etc and that was after waiting a few months before purchasing to see if some of the initial manufacturing flaws could be perfected.
The bad news - mine too has one pinhole. In the lower left corner in the margin. It's only obvious when I turn up the light. I'll have to try it at my normal lighting and see if I notice it enough to return it. So that's disappointing.
The good news - the lighting is consistent, the text is sharper (seems less like looking through a top layer), and the shadows are barely there. I really like the new firmware but need to play around some more.
I followed last year's threads and agreed with the issues that people were seeing. So if you suffer from color blob vision, then I think you'll be much happier with the new model.
