I have a spec of dust and a bit of yellow BLB in the lower left of the display. Other then those two things I'm happy too.Mine is rev A00 manufactured in Jan 2013. I use it for web browsing, gaming and movies.
Can't say a bad word about it really, I'm completely satisfied with the purchase.
All you whining peeps must have a really bad luck
You may have to look really close to notice the details that many in this thread are talking about. Though I notice that spec of dust from 2-3 feet away on a all white screen. Shoulda taken that as a sign to send it back
