Plus PC’s are PRONE to viruses.
I've had PC's for about 15 years. Built my own and bought some. Never once had a virus. Some spybots but never a virus. I've had everything from W 3.1 to now, Vista (which I kind of like). The laptop that's running it has 4gb of memory. A Toshiba that I got from Newegg.com for $599. I could get three of those for the price of a Mac.
