With the modern rhythm of technology development, it is very difficult to keep up with them. Even if you take a separate segment of mobile devices, then the novelties appear every week, if not every day. Now there is a trend in which the new smartphone is purchased approximately once a year, and if you take into account that the difference between the devices is not so noticeable and the main functions remain the same, and the price will have to be paid completely, then the picture is not the most rainbow. Recently, there are more and more ideas about the creation of modular devices in which the user himself can choose the necessary functions, as well as improve only with time. One of the last proposed concepts – Phonebloks, is now collecting funds for the production of commercial samples. The device has a basic part with the ability to install various modules on it and is very reminiscent of the LEGO designer.
