Situational awareness and semi-passive alternative inputs is being added to more and more devices. The always waiting your command "Ok Google" thing that Android phones and "Ok Glass" that Google Glass do comes to mind. Same for the XBOX One, only in that case it's also got a camera aimed at your livingroom. The Nest knows when there are people present. And now Facebook can listen to your surroundings while you post a status update. Any others I'm not thinking of?

Edit: Chrome now lets you use "Ok Google" as well.

I wish "Ok Google" was always waiting - Instead you have to initiate it.

It's pretty awesome when you've dirty hands and can't touch the phone, but you need to turn it on, and unlock it first.

I have a Moto X, it does have touchless always-on voice control: https://www.youtube.com/watch?v=YOr8Wxcc0Gs (I don't have it enabled, though)
