ipad vs textbooks [Infographic]

With Apple’s push for the educational use of the iPad the question keeps arising is the device really comparable to the good old fashioned text book? The main factors that are effecting this are the price of the device and the availability of it. Apple already has most of the major book publishers on board to made iPad compatible versions of their book’s but they are almost as expensive as the real book and people will have to buy the device on top. However is it more probable that they will replace the computers in schools rather than text books since the iPad can work as a computer in the class a well as a device that can view any text book published on it.
