There was a test of a B1 machine in c't magazine's display lab:

They determined the brightness at 64 cd/m2, and contrast at 82:1.  
However, due to the reflectiveness of the screen a high brightness is  
unnecessary and would only drain the battery, while the contrast is  
more than sufficient (newspaper typically has 10:1).
