Last year, I managed to convince 8 people to get Macs who either had not done so in the past, or who were coming back to the Mac from a long hiatus. Although I had for many years not considered myself an evangelist for "the cause", recent changes in Windows, the Mac, and the Internet have brought a change to that neutral position and now I appear to be pretty much a zealot. This despite the fact that I'm one of the few people I know who has both purchased and installed a copy of Vista. So, how do you switch your friends to OS X from XP? Good question, and tonight I've been finding out.
