Have this Notbook Asus F751MA-TY236H (New and sealed in original packaging) get in the offer of a supermarket for 399 (Euros). Windouws 8.1 is already installed, you only need to register, nor to build in my case a wireless connection to my Fritz box and then run the installation by itself. The first thing I did after that the Norton 360 online via my ISP installed. A few programs (Free) by Computer Bild downloaded and already it was ready to start. The installation has been relatively easy and very fast for me. The equipment I find against my old Fujitsu-Siemens with XP as a quantum leap in the development. How Gogo against BMW, or something. Am thrilled clear recommendation. Specifications can each read myself, about me I need not leave here. Greeting GGE
