Real reason: Finding a teacher who understands how to use or teach rpi is next to impossible.

Unfortunately, I believe Rpis sales were hype marketing that got out of hand. People thought they were getting a tiny usable computer at a great price. What they got was a bunch of chips that knowledgable people could use, yet the details go way over the head of the majority of impulse buyers. These buyers weren't missold, they just didn't have a clue what they were buying.

The lack of suitable teachers is a fundamental problem with the education system at the moment, not something the pi foundation can really be blamed for.

The "education" release of the pi itself hasn't happened yet, that's meant to be coming later this year / early next year from what I understand, and will be supplied with a lot more useful getting started documentation and software than you currently get.
