I've been putting off posting in this topic as long as possible, but I love Mac OS X. I'm planning on doing a hackintosh in the (very) near future, just so I can have apps like Coda, Espresso, and mostly Pixelmator. I'm on Win 7 and have used it for years, but I also had one of the 2007 macbooks a while ago, and loved it. I'm not saying one is better than the other, but Mac OS X really has some terrific apps. Also a Unix base is nice.
