Inkling Launches Online eBook Store
Ottway Ducard stashed this in edtech
I like Inklking; however, I think it's a stop-gap solution.
The future of learning is not in textbooks; digital or otherwise. Books, while a great form of entertainment and knowledge sharing, offer no feedback loop.
I think Udacity is pioneering the future of content, if for now at a higher ed level; and there will be other folks who offer the "Edutainment" piece which will further help folks learn.
It is, however, a great solution for those without 3G/high-speed internet access. That in of itself should be a world wide priority.
