The Lenovo IdeaPad Flex 2 15, also known as the Lenovo Flex 2-15, is a 2-in-1 PC developed and manufactured by Lenovo released in 2014 for the Windows 8.1 operating system (although I personally prefer Windows 7) with the necessary drivers for both Windows 8.1 and Windows 7. Depending on the model, it has either an Intel Core i3, i5, or i7 processor. It comes with a 1TB SSD, has a 15.6 inch transmissive LCD display and has Intel HD Graphics 4400. (Source: Wikipedia)
