You should point out that the HDMI pass through NOTICABLY degrades picture quality, especially with Tivo units. Also, it should be pointed out that the Xbox One's IR control of your TV and AVR is with power "toggle" commands only, NO discrete IR codes for "on" and "off"...which means that if you say "Xbox On" while doing something else (like playing a different console), it will SHUT OFF your TV and AVR. You should also mention that not all TVs can be controlled with the Xbox, as it lacks some codes for certain brands, like Elite. It also lacks the ability to learn IR codes...if your gear isn't in the database, it's not going to work.
You may also want to point out that the Xbox lacks the ability to control ANY DVRs. If you want to access your saved shows, you have to go back to using your regular cable box remote control.
For a device that is supposed to be the "center" of your living room entertainment experience, I find the capabilities of the Xbox One to be SEVERELY lacking!
