Yes, I'm not saying that the un-filtered i1 is not capable of making  
excellent color profiles with the appropriate software (Match or PM  
5).  However, if you just look at raw Lab data from an un-filtered i1  
your assessment of color or neutrality in particular for scanned  
grayscale wedges will not be the same compared to what you measure  
with a UV filtered device.
