Have ordered due to very positive reviews me the smallest version offered 2x 3000MHz, 4GB, Radeon HD 7480, 500GB. For 250 you can say absolutely nothing. It was Windows 8.1. pre-installed and everything went smoothly. I find it very convenient that the power button is so large - the nobody really can overlook. The unit is also surprisingly quiet from the fans here. As a finishing touch, the device has even a smart card reader for various SD cards etc. Office 2013 is Ratz Fatz and otherwise'm very satisfied with the purchase and would not hesitate to order it again.
