I will back up the first response to this post.
I used PCs for a long time. At one point I was running two systems that I was leapfrog upgrading every 6 months, liquid cooled and overclocked to get maximum performance. But, I switched to Mac shortly after getting an iPhone. When I did, I burned all my Windows bridges and refused to bootcamp or emulate anything. It either ran on OS X or it didn't get ran.
Shortly after that I upgraded my family and told them I was ceasing to offer windows support. I would only help them with Mac problems. There pretty much haven't been any.
So instead of digging out whatever went wrong this week, I now get to do what I want to do during that time. For me, the computer is no longer in the way. So while those hot PC's might be faster than a Mac, I was getting less done because I was fiddling with the computer instead of using the application I wanted. I have a friend working as storage support at Backspace who still spends half his time tweaking his PC so it will behave.
THAT is what I gave up when I switched.
