Just for your interest - I bought an Apple Cinema Display 23" yesterday and profiled it with a Spyder with OptiCAL. Here are the results of the profiling (compared with the notebook's 13.3" screen).

Good hard evidence for not using the notebook alone for colour & contrast correction.
OK I figured out how to post the image without external linking (I think...fingers crossed)

Yep-
I use it on location as a sort of "digital polaroid" for the clients and myself, and make sure that I explain that all should hold off on making any critical evaluations until I get back to the studio with my Eizo. Hence, I learn to rely on the "numbers" to determine highlight and shadow values.
