If you are a professional photographer or designer and you have anything to do with print profiles or displaying raw images, then you need to calibrate your display. Applications like Photoshop, Indesign, Lightroom and many others use the systems default display profile to display every image you see on screen. If you don't have a calibrated display, then you are working blind.
Teamed with a high quality display like the EIZO, you can confidently work on your images with the knowledge that the image you view today will look the same when viewed in 1 years time. In the age of Digital Photography, the monitor image is the only reference you have to the quality of your image.
