You are clearly not paying attention. To the best of my knowledge, you cannot buy textbooks on the iPad the same way that you can buy novels. A purchase implies permanent ownership. The fee that you pay for a textbook entitles you to use it for a limited amount of time after which it is no longer available to you. Mr. Incredible, this is called rent.It would be great to be able to RENT Textbooks, instead of buying them through an iPad. You're already dropping hundreds of dollars for the tablet, having the books be cheaper would be great too.
Like $4.99 a month to rent them.
