I just bought the Color Munki from X-Rite. Since it is a spectrometer it is working much better with the LED technology. Most of the pesky red is out of the skintones. It definitly works much better than the X-rite display tool. There is a definite lack of contrast after calibration that is still being worked out. Another concern is that it appears 2 stops brighter than it appears on a standard monitor. The new driver for Snow Leopard is great improvement but still has some kinks. Here's hoping that everyone will get on the same page soon so we can all stop worrying about it and shoot!
