I'm 27 and a MAC LoL. I picked up my first mac 12" ibook in 2005 and haven't looked back and now a 15" Macbook Pro. I have a XP desktop which hasn't been turned on for a while.
I spend too much time and energy trying to maintain my WinXP pc from viruses, spyware and usually go thru 1-2 x a year reformatting it. Not the case at all with my mac.
I'd recommend getting AppleCare. I learned my lesson when I had to replace the screen on my powerbook and it cost me a whopping $600. I just recently replaced the SuperDrive on my MacBook Pro and it was covered my AppleCare.
