If you get an Xbox One you have to connect to the online service every 24 hours to make sure you aren't doing anything wrong with the console itself. You also can't play a game that was on another persons console, so you have to buy a new game every time. You also cannot turn off Kinect and it is always watching and listening to you even when the console is off, because it is waiting for the "Xbox, On" command.
I was a 360 gamer this gen and really loved my experience on it, but I'm not getting Xbox One because of all the sh*t they put into it. Microsoft built a console they wanted, while Sony built a console gamers wanted.
The Playstation 4 doesn't have any of that crappy stuff the Xbox One has, and then on top of that they have better exclusives and it is €100 (dollars) cheaper as well!
I don't understand why someone would go with Xbox One, and I understand everyone has their own opinions, but if someone buys the Xbox One they are just supporting a company that is restricting your gameplay experience now and will in the future for more gamers.
Sony knows what they are doing, they are playing into the hands of hardcore gamers because they are selling a video games machine while Microsoft are selling a "all in one box".
I don't want an 'all in one box' - I want games!
(Also yes, I pre-ordered my PS4 yesterday)
