Again, if you are gonna chose and base your decision for purchasing a PJ based on screenshots, good luck to you.
Yes, Art spends more time trying to get the 'sharpness' screenshots down well, but they are taken at much different times over many months or years. He's changed camera's, changed how he processes images (raw format or jpeg, etc.), etc., etc.
Plus you can take 2 shots a second apart on the same PJ, and get different sharpness results.
Example The X10 vs a top of the line DLP that's considered one of the sharpest projectors out there, the $7000 Planer PD8150>

Planar PD8150: Bottom Line Sharpness
The PD8150 is excellent, the image is extremely sharp and crisp. A sharp, crisp image is a real strength of this Planar projector.
No question about the sharpness of the Planar PD8150, it is about as good as it gets!
Again, you can see that in the sharpness screenshots, the X10 Projector 'Looks' sharper. Do you really think it is
