Quote - If you indeed purchase a MAC, the very first thing to do is to reset your monitor gamma to 2.2 ....

Agreed, if you buy a Mac with OS X 10.5 (Leopard).

With the release of OS X 10.6 (Snow Leopard) in September, Apple are changing the default gamma setting to 2.2, so you won't need to change it yourself.
