Makes the complex task of calibrating your screens pretty simple.

I also calibrated my Windows systems and my laptop with no issues. Worked first time, but Mac dual screen support is much better than Windows. On my mac the dual screen supports just works, I use a single card with two outputs and it does support two profiles at the same time. I upgraded from the Spyder2Express, not really an upgrade because its cheaper to just purchase the pro version than it is to get the upgrade, which means I ended up with a spare device. I also print on an Epson 4800 so I need to know prints are going to look like my edits in Photoshop. It's wonderful to see all the monitors exactly the same. I am not one for photos or other 'screen saver' junk. The 2 CRT's are in my Green Screen Room and are used for direct video capture using Sony Vegas. All but 2 of my monitors are LCD so I could lean them back at a slight angle to have the spyder rest properly. As far as ease of use, I had no problems understanding the calibration proceedure Color Vision gave. I happen to work on 4 dual monitor work stations and several other single monitor computers so this was really worth the money. If you are like me, I always read many reviews on products before I purchase which helps me decide what to do and wonder about the people giving the reviews. I was shocked at how off my monitors really were (the Spyder2Pro gives you a before and after selection when you are finished). If you are like me, it's hard to buy something you are only going to use a few times a year so you think you can get away with calibrating visually with some of the freebies out there.

All you read about is how important it is to 'calibrate your monitor'. It was time to bit the bullet and really calibrate my monitors.
