From a detailed iBooks 2 review
This week, I tested a one-stop solution to much of that which ails textbooks: Apple’s iBooks 2. This redesigned iPad app offers enhanced educational textbooks that are, for now, focused on high-school students and cost no more than $15 each. Apple’s smallest and least expensive iPad can store roughly eight to 10 textbooks, along with other content. (High schoolers have an average of four textbooks a year, according to Apple.) The iPad itself weighs just over one pound.
These electronic textbooks include interactive materials that seem like they should’ve been available long ago: multiple-choice questions that can be answered with taps on the screen, embedded videos, dynamic diagrams that change with touch gestures and flash cards for studying important terms in a book.
