If you think that there is nothing cooler than IPhone, you didn't hear of a new YotaPhone then! A novelty with two...displays (a fully colored and a black and white one), which can both work as a modern smartphone and as an electronic book. Such a division considerably prolongs the life of the battery and saves the nerves of the user.
With all this, the design of YotaPhone is very well thought over. An electronic paper display made from solid glass is a bit curved inward in order not to harm the device considering our habit to put the phone with the color display upwards. To save the energy and your eyes any browser page can be easily transferred to an E ink display. For a while a double-displayed smartphone is presented in Barcelona only. But soon it will be be available for purchase worlwide.
