Except when you can't reply to a message on your phone cause you don't want people around you to hear that.

Let's be real, "conversational computing" may work in movies, but in reality you don't want people in the office or on the street hearing your interactions with your phone.

My thoughts too - it works in the home and at a push I can see it working for certain jobs, but it absolutely seems unworkable in public places.

But then I think again and wonder if maybe this is one of these things that seems unthinkable now but in 10-20 years, everyone everywhere will be doing it completely naturally, it's become part of the background noise of life, and nobody will care enough to really listen to what you're telling your computer to search for / do.

Yes on a silent train it might be awkward - but on the street I can honestly see it being fine, especially if attitudes and culture changes a bit as it's wont to do with new technology usage (see bluetooth headsets for a past example of this).
