I tried and end-around approach by installing XP on Vista, calibrating the monitor, and then pointing (or moving files) CS4 to the ICMs. After a prolonged session in a MS "help" forum and other sources I gave up on the dual-boot concept. After that I began profile/calibration research that ended up with buying the Datacolor Studio pkg of monitor/printer/projector hdwr/sfwr. Although I have read quite a bit about color management in books, articles and posts, I still consider myself a novice in that area. If the print has what I want and accept, then on with life. After getting down to either the Colormunki or Spyder3, I chose the Spyder3 and not only am very pleased with the complete product, but the online support from Datacolor is incredible. I do not use the term lightly having supported Access for MS 12 years from its intro. The problems I had were some tyro boneheaders, but some were from the UI of the software. No showstoppers, but real issues. Some of my suggestions were actually added to the 4.1 version, available I believe in beta from the Datacolor site. I highly recommend the product as an intuitive, instructive, versatile and cost-effective means of monitor calibration/profiling and printer/paper/media profiling. Now I really enjoy and understand better my Artisan and 2200 photo team. I have attached a small xls that helps me with understanding my paper options and a little more understanding of CM.
