I would turn to Mac anytime if it has the 2 buttons-mouse for right-click (or left-click for left handers). Totally in a heartbeat but unfortunately, I'm used to PC. In fact, I do have a macbook but it's used once in a while when it comes to editing with pictures and/or videos. And also, some programs that are designed for Mac only like for instance: Pwnage which always releases first before WinPwn, a similar version with different codes for Windows. =P
So, I can't really choose Mac or Windows since they are two different system platforms. They do both have pros (strength) and cons (weakness). So they are good, depending on what and why I plan to use for. I would recommend Mac but again, I would still say go for Windows, too. On the safe side, let's just say get BOTH and the battle's over and OLD. It's nothing new. The rivalry between them just rekindled and started on competing against each other. Who knows, Mac accused Windows of stealing their ideas or was that Windows' ideas? You can dig in by researching, say, GOOGLE or yahoo, whatever engine search you are using. =P
