Apple has had voice commands on its mobiles, too, for quite a while. But this is of a different order. I think Siri will be huge and the other phone manufacturers are going to have to start playing catch-up. Apple describes Siri as beta which is unusual for them and there are clearly limitations and some glitches with it at present. But most people using it seem to be very impressed. Apple and Microsoft are both very interested in this type of AI and are putting serious money into it. You may not like Siri but you won’t be abel to ignore it or similar developments whichever platform you use.
