I disagree, even, that the commercials are stupid. Stop thinking like a computer expert and think like an average consumer who wants to do computer-y things. All of the computer experts already have a likely unchangeable opinion on Macs. These ads are for the average consumers. I think that targeting your commericals that specifically makes a lot of sense.

The commercials show random ordinary people who proclaim in very simple terms why their Macs worked better than their Windows machines for them. Most people don't want to know how computers work. Many people don't have computer expert friends to fix things up for them. Many computer experts are tired of going to their friends' houses to do so.
