In May of 2012, I got an iMac. No, I have no care or need for a refresh, and Ive been using windows for the past 6 years, when a new OS comes out for windows (Vista, 7) its all hell breaks loose. Drivers, Incompatibly, and just a nightmare. Now, with Mac what am I expecting from 10.8? Im looking to upgrade the second I see it on the mac app store.
