For students, a textbook with that iPhone?
The Apple (AAPL) iPhone App store already has over 60,000 products and one billion downloads. It is about to get a new set of products that should do especially well. iPhone users will be able to download up to 7,000 different textbooks onto their handsets, making "education everywhere" a reality.
The e-textbook application may be nearly perfect for the iPhone crowd, but unless CourseSmart is willing to spend a lot of money, who will ever know about it?
