Useful devices. Amazon Kindle 4.

      Personal development. 

     I present to your attention a very useful device - Amazon Kindle 4th Generation.
     The device was bought in 2011, a few months after the release of the US market. I ordered the full version without ads. At the time of the purchase price was 120 $.
     For those who are interested in self-development, this device is indispensable. First, let's think about the environment.
     1) Felling of trees is reduced, when we read the e-books instead of paper.
     2) The price and availability of books in electronic form.

There is another bonus for people in developing countries. For example, I have to flash your device and set Coolreader program that allowed me to read all of the existing e-book formats.
     Using the device is very convenient. Acquired pouch and carried with me to work. I read on the way to work. Places takes a lot, weighs a little. Who reads all formats.

     The result of 5 years and the use of some positive emotions. It happens sometimes spontaneously reboots. But all this stuff. The case of the intensive reading is wiped.
