I don't think this is a bad thing besides damage to the eyes and that doesn't even effect your eyes too much more than normal books. Book stores are being replaced with virtual book stores and the jobs are being replaced.
A good thing!
I'm not saying you're fat... but if i had to choose the 5 fattest people i know, you'd be 3 of them.
I honestly love real books more than the e-books, but I have to say that they are okay too. I don't think book stores and libraries are going to close anytime soon in this lifetime, I hope.
I love book stores and libraries too, I just find a book and stay at one for, like, a few hours. Like a home away from home ^^
