Reading textbooks on ebook reader!! Well I wonder that I am not the first with this Idea. I am reading lots great eBooks (by Walter Greiner) on my desktop. Well, I am so impressed by those books that I have decided to use them as my textbooks. But the problem is I can't sit in front of LCD for so long (for 8-10 hours). So I am planning to buy an eBook reader. Just tell me is anyone of you is using it for the same purpose as I do and/or how greate eBook reader are at viewing pdf files specifically equations. My pdf files are not of high quality, as I will have to convert them from djvu format. and what if I convert pdf to azw format (official format of Kindle).
