I've just installed de demo, from X-Rite website, and with my Eye-One meter only the monitor calibration works. I tried that and with Apple monitors (only brightness adjustment) it works very well. If you are not using the L* type gamma i can say that is better than ColorEyes. But the fun stops here if you have a good monitor with gain controls, because i1Profiler does not let you balance the color temperature from your monitor. At least in manual mode.
Anyone tried it with an monitor supported in auto mode?
