I just discovered the Colorsync Utility in the Applications/Utilities folder. It allows me to visually compare the measured monitor gamut (using my calibrator) to standard sRGB and aRGB as well as to various printer/paper/ink profiles.
I've done a search on this forum and didn't find anything on this topic, so I thought I'd point it out.
