Interesting piece on NPR this morning about Barnes and Noble re-acquiring their spun-off college bookstore company and investing in electronic books. As the Kindle and smarter phones continue to add features for reading electronic documents, textbook companies hope to deliver their media over them (at the same time, they look to change the business model from product to service so that they don't lose so much from resellers).
James Lombardi, CFO, is quoted as saying that although he's old school, the kids will be into it:
I don't know if I would have been able to do calculus derivatives on my telephone, but it's certainly going to evolve.
Once the iPhone adds Flash support I'm sure more interactive textbooks will be available on it. And of course Wolfram|Alpha is already here, putting the full power of Mathematica on the web.
In the future, instead of sore fingers from writing, calculus students will all have sore necks from squinting at their tiny screens.
