Which device is the right one for me?

The kind of reading device which might be right for you depends on what type of person you are:


The bookworm

You devour one book after another - especially novels - therefore you wish to have the best possible display for the text? You like to read your book without any distraction from other apps or functions?

If this is the case, you should get an eBook reader with an eInk screen.


The practical type

You do not want to carry different devices with you when one multi-functional device offers it all? You are a frequent or an occasional reader. Wherever you are there are always enough power outlets, so that a low battery life is no problem for you? If so, a tablet or smartphone is the right device for you.


The expert

You work with non-fiction books, maybe you are even writing a thesis, and would like to use excerpts from an eBook to paste it right into office software? If this is the case, a laptop or PC is best suited for you.
