Summary: Of the two I've owned, both leave image burns constantly. It's just not a good monitor for doing any kind of professional image or video-based work. It also requires a $100 cord to hook it up to any modern computer, the 3rd-party versions of the cord don't always work or perform well.
very big, but just doesn't have the reliability it should

Summary: The power supply died after three years and, after about four years the screen started to delaminate, leading to a discoloration creeping from the lower-left hand corner of the screen. For the price I expected something more robust.
Summary: I use the Apple Cinema 30-inch display at work along with two 24" NEC Multisync 2490WUXi displays. Our systems are beefy HP workstations running Nvidia Quadro FX4800 cards. We use our Apple monitors as essentially a 3rd display for extended desktop space.
Summary: I've owned the Apple Cinema 30" display for several years now and I kept Applecare on it until the warranty ran out. The display is beautiful and provides a ton of real estate on a single display. However this display did not age well.
Summary: LCD monitors inherently can be manufactured such that they end up with a few dead/bad pixels. This shows up as a colored dot on the monitor when certain colors are displayed. Apple needs to do the right thing and take a stand on quality control.
