Future book

I think that in the future all the books, is to say, the syllabus will be in internet. It will not be as now that only scan it and hang it but that it will be interactive. They did not need books therefore it will be more economic. One the this disadvantages is that you finish with headache. One avantages is that you can just take a lot of books on the computer, so you do not need bring often a lot of books.
