I agree with you, higher prices are disappointing. However, given the example you used of Campbell's Biology, most of the time students never read a textbook in its entirety. In that case, Inkling actually lets you buy the specific chapters you need. I'd bet for most students, that model will be cheaper than buying used textbooks (of course, I don't have any hard numbers)… Plus you get all the 'bonus features' of an Inkling book.
