Science and technology development so fast, we even can?t follow their footprints. In order to not out of date, we always change our Electronic products, as well as the app. Nowadays, I loaded the Laputa book reader app. I think is terrific! Reading on this device is a good way, even in the dark. For the reason that I like reading in the dark, it is quite, and you can completely immersed in it. If some guys have the same habit with me, you can use it by yourself, you will never regret for it.if some guys have other good ebook reader, please introduce it to me! thank you very much!!!
