notebook display for image editing?

Not much unfortunately. But the press releases boast considerably increased viewing angles. Could be mere marketing of course. But on the other hand, I can't really see who would buy an expensive 137% AdobeRGB gamut display if viewing angle issues etc. make it useless for serious image editing.

yes, this is commonplace knowledge, which was applicable for a long time. But ... as of today?
Did you check the link? What about the Sony VAIO AW with 137% AdobeRGB coverage ?

I don't think there is such a thing as a "high-end wide-gamut notebook display for color-critical image editing". Not yet, at least.

High-end color-critical image editing should be done using a good-quality desktop display -- well calibrated and profiled, of course.

Calibrated and profiled laptop displays are better than nothing if you are on the road and have nothing else handy -- but at this time they are still very limited in their capabilities by very narrow viewing angles, lack of uniformity, and overall lower manufacturing quality standards, also due to compromises that allow for a lighter and more comfortably portable CPU.

And any experience with one of these notebooks? :
