The OLPC project was the subject of much discussion. It was praised for pioneering low-cost, low-power laptops and inspiring later variants such as Eee PCs and Chromebooks; for assuring consensus at ministerial level in many countries that computer literacy is a mainstream part of education; for creating interfaces that worked without literacy in any language, and particularly without literacy in English. It was criticized from many sides regarding its US-centric focus ignoring bigger problems, high total costs, low focus on maintainability and training and its limited success. In 2014, after disappointing sales, the Foundation shut down.
