As a designer by trade, I've been using Mac OS exclusively for the last...oh...13 or 14 years. I have only touched Windows on very rare occasions.
Just bought my wife a HP laptop (she doesn't like change and Windows is what she's used to). Vista can bite me. That POS has frozen, hung or crashed more in the last week and half we've owned it than in the 2.5 years I've had my latest Mac.
I work in marketing, so I always took those Apple commercials with the Mac and the PC with a grain of salt. Entertaining, probably partly true, probably exaggerated. What do I know? I haven't used Windows much since 1996.
Hell no. They're so accurate it's scary.
That is all.
