If you can't bring yourself to make the change, you can also preview Window/Mac gamma by jumping from Photoshop to ImageReady (Apple-Shift-M) and selecting Image > Adjustments > Gamma from the menu. There is a handy feature that lets you toggle between gammas.

Great tips! I'd like to add one more, taken from the macworld.com forums- you can view the gamma difference by using Photoshop's "Proof Setup" command and set it to Windows RGB. (View->Proof Setup->Windows RGB) This will darken your monitor to simulate the Windows default. Theoretically, this is the same as using a 2.2 gamma monitor profile but you have to remember to set it.
