I'm a PC user who converted to Mac. I had to for my career. I've had a Macbook Pro for three years now, and not a single hardware problem, or a virus, or anything to speak of that qualifies as a reason not to get one. This post feels really unhelpful LOL, but I just haven't had a single problem to speak of, and I found the Mac's OS pretty easy to get used to.
I had XP for three years before this Mac, and I probably wiped the hard drive every six months due to all kinds of silly issues.
Best of luck! I love computer shopping.
