Gosh. I just fired up my Toshiba running Windows XP after a year of laying dormant. Why laying dormant? Because I bought a Macbook for Christmas last year. I'm able to see the screen on the Macbook. The Toshiba has a cracked screen from having cans of beer thrown at it. This after getting a virus for the third time since owning it for two years.
I figure after you take it in to get the virus removed at $100 a pop, it's worth the extra few buck to buy the Apple.
