Ebooks readers

And also on smartphones and especially the tablets.

But it's best to read on special devices - e-book readers. At once I will notice, that color devices electronic books - cheap and very bad. They brake, are inconvenient and in fact are weak tablets.

E-ink - electronic ink

There are also classic readers with electronic ink backlit. The fact is that the classic readers do not shine the screen and we need to take care of the lighting itself, as with a regular book. There is not enough battery for a month, but for a week or two.

Battery

Dimensions

1. Compact.
2. Medium size.
3. Great size.

Medium-sized - books are easy to find, the optimal solution, you can wear yourself and the screen is normal.

Large size - suitable for those who like large text. Not comfortable to carry around. I recommend only if such a screen really is needed. You can not carry this with you in your pocket, you can only use it at home or bring it with you on vacation and use it there.

Amazon began selling printed books online, and then one of the first to engage in e-books trading. Amazon also created own reading room and own format. The reason is most open source formats, and their purpose was to protect copyright.
