Well, it's not like all the reviewers attempt to scratch it. The author of the MySymbian preview only scratched it because of having sand grains or something in his pocket. His N900 didn't come with any protected film, other review devices may have them.

Anyway, what we need is someone/reviewer to "stress test" the screen like how they did with the N97: http://www.youtube.com/watch?v=kB1GxqRFKzw
