I'd like to do a "Should you buy a Mac?" speech for my Toastmasters club. I'd like your help on this: what are the best selling points and also the biggest drawbacks to using a Mac over a Windows PC? My audience is 'normal' folks--people who use computers at home and work but don't become emotionally involved in them, like (ahem) some of us :b So I could use ideas geared toward the mainstream user. Thanks!
