Only negative, once you have it profiled, it matches the printed output well in Qimage and other color managed software, but in the majority of software, including windows itself, your photos will look oversaturated.
This is because it is a wide gamut monitor, probably close to Adobe RGB rather than the usual sRGB.
I have recently bought an Eizo monitor; they overcome this problem by having various modes available: Custom for utilising the calibrated settings, sRGB for web browser etc. use, Text for word processing, e-mail with a lower brightness and so on, 5 modes altogether.
The mode can be controlled manually with a button or automatically, based on active application, by Eizo's Screen manager software.
The other useful feature is the automatic brightness control, based on the ambient light. I can now get consistent results when refining images, whether I do it in daytime or with artificial light in the evening.
