Not true at all. Macs ARE PC's. They use the same exact parts. So yes, you can compare them spec for spec. My tests, on the same machine, Windows wins when it comes to extracting large files(greater than 4gb) and in gaming even with native games such as World of Warcraft. It yields better FPS in windows. Video conversions area also faster in windows on the same machine. And when I was doing large extractions with macpar deluxe the system would hang so I couldn't do much else at all. I found I was staring at a spinning beach ball more often than i'd like. And it was certainly no more stable than windows. That said, I do like OSX. I could list a number of reasons why it's better than windows. And a number of reasons why windows is better.
