I am starting back to school this summer and while looking at my first class I noticed I can buy the text electronically for a savings. I like the idea that I can have a much smaller device for my books. I am constantly traveling or away from home 12+ hours a day, a big textbook is just one more thing to carry. Has anyone used e-texts? This is so different from my first college days just 8 years ago! I am interested in the Nook mostly for the color option if I go with text books. I am going to nursing school so lots of diagrams.
