These Ads will only be effective on those who are uneducated. In actuallity they're not comparing mac vs pc, thats just silly. That would be a hardware issue and these commercials have nothing to do with hardware. Infact we do not even see product except to flash the logo.
What ther're really comparing is the operating systems. You dont hear the word windows though, you hear PC. And last I checked that was short for Personal Computer, pretty big umbrella I think.
They dont discuss specific features in software or hardware, just capabilities. It's completely an emotional sell, (But what isnt right?),
