Don't worry Quagmire - once you get the hang of Macs, you'll fall head over heels in love and you'll never, ever turn back.
I switched from PC to Mac this past August after using PC all my life, instantly fell in love, and will never, ever, ever, ever consider going back to PC, or using any operating system even remotely associated with Microsoft.
Every three or four days of my life up to about August 2008, an incident would happen with my PC (anything from a simple "ERROR" message to a full blown system crash) that would strongly tempt me to throw my PC into the pool in my backyard.
However, after making the transition to the "other side" in August, I have never been happier, and I found that my overall blood pressure has dropped
Anyway, for me at least, the quote rings true: "Once you go Mac, you never go back".
Don't give up just yet ;D
