I'm considering buying either a Xbox One or a PS4 for playing next season's games (like FIFA 2016). However I'd also like to buy a new computer to play Windows games (like Blizzard's new game: Heroes of the Storm). Unfortunately I don't have money for both things. Hence the following question:
Is it possible to install Windows on Xbox One, connect a keyboard/mouse, and play on it normal windows games, as if the Xbox One was just a PC? If not, why?
