I’m a fan of iTunes you but it’s is limited. I know they introduced “courses” which are cool, but it’s only documents, videos, and apps. You don’t know who else is taking the course, or a way to contact/interact with the professor. Piazza plans to provide just this. It looks awesome and I hope the beta test with the Stanford iOS development class goes great and they offer it up to other educators for their courses on iTunes.
The other feature I want, is a test & quizzes feature like those found in course management systems. It doesn’t need to be that advanced, but it would be much better than posting quizzes via PDFs.
