My mate cancelled his Xbox One pre-order, as he is not really convinced that this is the way forward as an all in one home entertainment console, for use with the family TV. He has both PS3 and Xbox 360, but neither these are located in the lounge by the family TV, both are in the "play" room, to play games whilst rest of family can watch TV. He has a FreeSat recorder box, Blu-ray player and Smart TV and between them do iPlayer and LoveFilm and Netflix (?) and play disks so why bother with yet another box.
He went for Xbox One (as opposed to PS4), as was originally touted that downloaded purchased Xbox One games could be played online with your "friends" without them having to purchase the game, unlike PS4, where both players would have had to purchase the game. Not sure that is true now. This was his major issue with all the on-line game play, that all of your friends have to had purchased the game, which more often than not they hadn't. Wasn't too interested in playing "just anyone" as they were always better than he was, which was strange as in 1990's he got a ranking in UK DOOM championships, held in London.
