I think it looks pretty cool, but I'm still not big on voice commands. After more than a decade, it still looks stupid when you see someone walking along having a conversation on their bluetooth headset, and I don't really want to be announcing the content of my text messages or searches. For these reasons, I'll be very surprised if voice control becomes the norm in mobile technology.
Yeah, the speaker in my old phone was rooted so I had to use the earpiece to make calls and I felt like a right dick just standing there talking to apparently no one.
However if EVERYONE is doing it and knows what's going on then I wouldn't think it would be such an issue.
Until I can just talk to my computer or phone or whatever and have it automatically recognise when I'm talking to it, or talking to another person then I cbf pressing a button to make it hear me, then wait for it to recognise me, then start whatever app it is. I'd rather just press the damn button to start the app myself.
