I went for a PS4, I had the Xbox last time and didn't really get much use out of it, I bought the kinect and thought it was absolutely shite, so wasn't bothered with cameras this time around and wasn't interested in the media stuff as I don't see the hardship in using the remote to switch between the sky box, smart TV etc.
As someone without much of clue, what I read pointed towards the PS4 bring better for gaming and at a better price, so far I've just been playing FIFA and bits and pieces on Killzone, which I'm not a great fan of, but it seems a decent console.
I'd probably be better suited to a PC as the games available are much more my cup of tea, but I can't be arsed with the messing about and seemingly constant upgrading that is required.
