None of this has anything to do with my point. E-ink reads like paper, as in it does not hurt the eyes like LED or LCD screens do. The screen type is designed in a specific way. Typos are the issue of the publisher,
not the device. I have some paper books with typos in them.

And my Paperwhite's battery lasts several weeks with heavy use. I've done a great amount of reading on it, and it is very handy when travelling. I love a good paper book, too, though. I'm just saying people who are opposed to e-readers don't have much experience with them. I can't read a paper book without a light, for example.
Also, authors make more money off ebooks than paperbacks. So either buy hardcover or ebook to give them more money.
