Linux: The power beneath
Re: Ok Google question
Because it would quickly drain the battery. Think about what you are asking the phone to do:

That is a LOT of stuff. The way the Moto X gets around it is to have a special hardware circuit designed to do ONLY that, so the rest of the OS and phone can continue to sleep. At the moment, no other Android (or non Android) device I know of does that. Will other devices add it eventually? I don't know. Personally I find it kinda creepy.
It is also the reason that unless you find that function/gimmick very useful, you should turn it off on your homescreen/launcher because it will suck a lot of battery there too. And let's face it, if the phone has to be "on" anyway, pressing a single microphone icon is just not that difficult...
