Thanks for the confirmation, I've suspected this for a while now. We've had three occasions where my wife could not get voice command to turn things on in the morning. When she used the power button, the UI came up but TV connection was broken. Only thing that fixed it was powering down, disconnecting power, then plugging it back in and restarting. Not a good way to start the morning and my wife is ready to relegate X1 to the den, which really defeats the whole purpose of getting an X1. I've noticed the UI consistently lagging for a couple of days before this occurs, I will try to be more proactive and cold boot it more often. Hopefully there is a fix soon.
