If it's of interest I've just written up some notes about the new ColorMunki Display
http://www.northlight-images.co.uk/reviews/profiling/colormunki_display.htmlIt's a bit longer than usual since I've tried to address a few more of the basic 'why I should use it' issues. As such, it may err on the side of simplification for some of this forum's more knowledgeable members, but then it's written for a wider audience ;-)
Since I've now got both the i1Display Pro and ColorMunki Display devices here, it's been interesting to compare them in use. I was surprised at the level of functionality found in the ColorMunki Display - more than enough for most users. The software is also noticeably easier to use than the still somewhat '1.0' feel of i1Profiler.
In terms of profile accuracy, I couldn't see any real differences between the devices - however I don't have the necessary equipment to measure this absolutely, or the patience to get into real quantitative analysis of the numbers - fortunately there are others that this sort of thing does appeal to ;-)
I set up a projector with the ColorMunki Display and also both the i1Display Pro and i1Pro+Beamer (using i1Profiler) - all three produced virtually identical results, with a slight over saturation and loss of detail in saturated areas. Much better than with no profiling, but I know the projector can do better...
