Hey, at least the features are there if you want to use them.
Some mixed reviews coming out, mostly positive but with the odd mention of slightly glitchy Kinect operations. Some of the reviewers have noted that they're on beta OS though, however the same was probably true of the PS4 reviews. I'll post two of the best reviews of each console here, at least IMHO:
Polygon PS4 review
Polygon Xbone review
Both seem quite fair. I'm still sure I made the right decision for me, although I can see why some care little for Kinect and the extra cost.
