I decided to try buying my books as Ebooks this semester and it was definitely a good idea. My college gives every full time student a Mac or PC and this year they started adding iPad minis as well. Now I will always have my Ebook with me and I don't have to worry about lugging around 20+ lbs of books. I'm saving about $150 compared to buying used books, $300 if I bought them all new. And even better with this Comm Theory Ebook I was able to rent it for just the semester. It downloaded in just a couple minutes to both devices and I don't have to worry about returning it cause it will return itself. I would definitely suggest trying this to all college students. I'll try to add more at the end of the semester to say how it all worked for me.
A caution of warning, make sure that you only need the book and no other online resources that sometimes come bundled with printed versions of textbooks. I don't think that anything would come bundled with this book but I have seen reviews complaining that the customer also had to buy a separate item for other classes in different subjects.
