Come to think of it for dual monitor calibration it would be nice to
include a standalone "Measure" function in the software, that would
just measure the white point and luminance levels. Would be nice to be
able to save it as a target as well so you can load it for other monitors.

And I don't see why would somebody argue against the strengths of
their own software.  I understand  David Tobie is trying to correctly
represent the capabilities of the software but the thing is a lot of
dual monitor calibration functionality is available in XP for Spyder2
Pro users even on an AGP dualhead card.
