I used Khan Academy through college and still reference back to it for university work if I'm not completely sure on a methodology. There are also dozens of other resources from around the world (so different styles and different syllabi), so I learned to answer the topic, not the specific question, which was better for education and meant I could apply it to different scenarios.
I think the problem might exist with not having centralised education. It's hard enough to get a kid to do their homework let alone focus on a tablet or PC without switching over to something more enjoyable. School, while it has its flaws, gives a focus and separation from the rest of your life. If everyone went over to Aristotl-e, what happens when you get stuck or can't access the information? How will you assess students and how can you make sure they're on track? Peer focused study is also very beneficial to social and academia, so how will this fit in?
I like the idea of shaping education to a person though. We need different skills at different ages and are more capable of learning those skills at certain times too. I think technology should compliment education and students need to be aware of these alternatives (they need to learn to learn), but it shouldn't become the main source just yet.
