Ok here's just a few on the reasons i'm not plugging anything up to the HDMI out on the Xbox One
1. Can't control DVR functions on cable box.
2. Doesn't output Dolby digital surround sound from HDMI out (or even optical out)
3. Voice commands inconsistent and unreliable. Stated on REV3's review, The Verge's review, and Engadget's review.
4. Noticeable controller lag on HDMI out.
5. Doesn't interface with other devices in the living room (other game consoles, HTPCs, ect)
6. A guy on the official forums asked about AV receiver control and the question was ducked by tech support.

yeah this thing might revolutionize your living room if all you have in there is an Xbox One, a cable box, and a TV but add in other game consoles, a HTPC or a home theater system and it fragments your setup because it can't interface with all of it.
I think the console is fine. I thought it was fine when it was all digital actually but i think the media functions are junk. cheap parlor tricks to impress simple minded people or people who don't know better. set up your room properly and a Logitech Harmony remote will do a much better job controlling everything possible to be controlled through IR and possibly even the PS4 in the future.
