Apple announced the software and are really keen to see the iPad take over as the way books are carried around by school kids. The much reduced weight that have to carted around will likely turn them into a bunch of weaklings with the lack of exercise not having to lift heavy weights anymore, but at least their brains might grow with the improved learning that will come from more interesting material to wade though. They will be able to better regurgitate the knowledge for the tests and exams that they will still be forced to endure. Poor sods!
