Online e textbooks

No i dont think that e online books are useful in many different ways, but the main ones are that it leads to many distractions, isn't as easy to use and cant mark or highlight as well. This all leads to not paying attention and being inattentive in class and if there is anything in short supply among students theses days, it attentiveness. online textbooks arent good in a study form because it is harder to figure out how to write notes and highlight words and phrases that you dont understand or that are important and useful. With a regular textbook you can do all of that and be more aware and not get off track into other things that you could do on a computer or tablet that you couldnt do with a regualr textbook. Ive never used them before but i am 50/50 when it comes to how interested and excited i am about them. it would be nice to not have to carry around big textbooks and pull them up on any computer, but i wouldnt like the way of how i cant mark up the pages and write notes to myself about the reading. Also the attraction of either do my reading or play angry birds for hours.
