For my economics class at college, I have to write a short paper on an interesting behavior that can be explained economically, such as why a gas station across the street from another charges 10 cents more. I decided I'd like to write mine on a behavior that Apple has exhibited, but I'm at a loss... any ideas? One thing that they've done that I can think of it to not implement FM radio usability in iPods for years, a seemingly simple task... but that's a really weak topic I feel. Any suggestions on an interesting decision Apple has made I can write about?
