I think the problem is with the X1600. It has the same dithering problem, not a sparkle effect like some people are saying, I dont even understand what they're talking about. Okay maybe there's two issues: sparkle and dithering, but I would like to see the dithering problem fixed, like the ASUS computers etc. It has been widely discovered that ALL laptops with X1600 have the same exact problem. Why would be MacBooks Pro's with X1600 be any different? The issue is exlained (and the fix for ASUS) very well here, please read:

Or go make a Google search: "grainy x1600"
Ofcourse I'm also aware that the MacBook Pro screens are crap quality, but still with BIOS update I think we can fix the worst issue.
Does Apple people ever read this? Is there a email for a tech support, or a developer team?
