Seeing this reminded me of a Microsoft focus group I was invited to be a part of a few years ago. As a CTO who had decided to build everyone on top of free software, they wanted to know what it take to make me to switch to a Microsoft stack. I told them they were 10 years too late. You see, I made the decision to use LAMP stack not because it was cheaper, but because it's what I knew. And the reason I knew LAMP stack was because that's all I could afford when I was 15. The question for Apple isn't whether businesses or experienced developers can afford their development tools, it's the teenagers they should care about. And while, $5 is still well within the average teenagers reach, it's still a lot more friction than free. This decision seems short sighted to me even if the effects of it aren't immediately apparent.

Schools such as Caltech and MIT have rigorous curricula that proverbially requires constant study every day of the week just to stay in the middle of the pack. Naturally, most students cut back on sleep. Proponents of this approach are aware of this, even boast about it, saying that this is the best way to learn the material.

On the other hand, numerous studies -- including the link at the top of this page -- conclude that this is the worst way to get anything done.

They can't both be right.
