I dithered for many months before taking the plunge and purchasing one of these. At full(optimum) res., it is a great monitor. Not so great for HD movies as the image is not functioning at the optimum res., being 1080p(for HD movies) - most 1080p HD TV's will give you as good if not better results.
I run two systems off of it ..... 1 MacBook Pro 17" at 2560x1600, and 1 Linux Mandriva 2009.0 also at 2560x1600, both for images and desktop publishing, and each into it's own DVI-D. The results are stunning, and colour separation appears to be extremely good.
The default DVI cable despatched with it is not sufficient enough to support full 2560x1600 res., so you will need to purchase a replacement/additional cable with full DVI-D capability.
The HDMI connection when viewing movies is a far better option that the DVI-D connections.
