Don't know.  I bought an HP 14" "wide" screen notebook  to take on photo 
trips, and use a Lenovo T series for business.  I didn't think either 
one was particularly useful for critical viewing, but then I haven't 
calibrated either one.  I just wanted the HP to download cards and then 
back up to an external portable drive.  My PC monitor is calibrated with 
a Spyder and ColorEyes and is in a consistent light environment.  I 
thought it would be really difficult to get good results with a notebook 
with varying lighting, slightly different screen angle and all that.  
Others may have better results.
