I have just calibrated my Dell 2408 LCD panel with Colormunki. It went without a hitch. I tried both the EASY and ADVANCED modes and both are as straightforward. I next profiled my Epson Stylus Pro 4000 with Premium Luster 250 paper. I found the process simple and fast. The resulting prints are also much better than the prints I made with Epson's canned profiles.
The only thing I look forward to is for X-Rite to polish their software further. Small improvements like allowing me to move the target area for the spectro would be nice since OSD for some monitors don't allow you to position the display off-centre and can be a little inconvenient when making adjustments. Other than that, I'm most happy for what I have bought. I had for so long wanted to buy the Eye One Photo to do this profiling but found prices to be high and read that scanning back the printouts from the printer to be tedious and slow.
I'm doing this on a PC running Windows XP SP3, Quad Core on ASUS P5Q-E, with 4Gb RAM, for those worrying about running Colormunki on Windows.
