I'm a little upset with my experience with Apple Displays. I currently own 4 of them, 2x20" Aluminum ACDs and 2x23" Aluminum ACDs. Every one of them has some sort of display issue after only around 4 years of use. MOst are extremely dark, one of them has very strange ghosting issues, etc. I'm wondering if I should be jumping ship and going with something else? I see some amazing Samsung displays for $300 that look as good, if not better than the Apple Displays. What I can't figure out is why, other than the built-in camera, would Apple be asking so much for their displays?
