Here's a great quote:
"Why run OS X? Well, when you are just used to Windows, it is like living inside a house and not experimenting the whole world out there. Once you get out of it, it is just amazing. Mac is just that: You just feel like glued to the computer. Everything is just beautiful, the interface, the stability. Once you experiment it, you don't want to go back to windows. Trust me."
And the best part, this is from a Windows user who got Leopard to run on his PC hardware.......
