I remember reading before this was coming out that all the touchless OK Google Now stuff was processed in the phone processor, ie, you didn't need an Internet connection for it to work except for things that actually need to access the Internet. For example, if you said "OK Google now, text XY" it would just process the command in one of those onboard processors and set up the text message.
But, I've noticed that instead what happens is that it goes onto the web and then processes the command. In fact, of you go on the web and look at your search history, every single Google Now command you had spoken is there. So my concern is that you incur data charges for ANY Google Now command you speak, whether it's just to call someone or use the GPS Navigation, etc. (Also a concern is that of course Google is data mining you). And this is especially expensive if you are overseas and using the command not knowing that you are getting data charges.
unless, of course, I'm missing something....anyone have thoughts on this?
