Kudos to Sony for rejecting always-online and DRM. I already knew I would not be purchasing an Xbone, but I will probably get a PS4 in a year or two. Very similar specs, but PS4 doesn't require online (which means Mincrosoft could end Xbone access in the future), no DRM (right of first sale FTW), and no always on, possibly always-spying Kinect. And, to add to that, it is $100 cheaper.
And if you haven't seen it, look up Sony's "How to share games on the PS4" video. It is amazing.
