Check out what I got my PC to look like. It is still running Windows XP, it just looks like a mac. I even found themes for Firefox and Thunderbird to make them look like safari and Mac Mail. I could have just downloaded Safari for Windows but I don't like it that much. EDIT: Here is how I did it: http://features.engadget.com/2004/06/09/turn-your-pc-into-a-mac/ To change most of the icons/log-on screen/boot screen, I used a free program called Fly-A-Kite OSX. Google that. There is more you can do to REALLY customize it to look better but it takes lots of time. Enjoy!!
