I figured out why I dislike Apple, and the average person loves it.
The Apple design is anti-nerd.
It allows people to use technology without being ashamed that their skill is rudimentary. It puts regular folks on equal footing with skilled users. It is the intent of the product that its uses are limited and basic. By design, it lacks advanced features and flexibility, so that it cannot be used more effectively by being good at it. It's not just the low skill threshold; it is the low skill ceiling that makes people want to use it. Some uncool, nerdy person can't outskill you at iTunes.
Then, it's pricey and stylish, and therefore a fashion statement: something nerds don't know how to use.
It turns the table around on nerds. Therefore, normal people love it. Genius. :)
