In the 1980's there was a TV show called Knight Rider, where Michael Knight, a vigilante with his car K.I.T.T would fight bad guys. The thing that made this show special to me was the car. Mr Knight could talk to it, and it would understand what he said and meant and respond meaningfully. Sometimes throwing a witty remark in there. It gave the car, a personality, it was the co-star of the show.
Now in 2011, Apple released Siri. An assistant where you can ask certain things, like "What is the weather going to be like tomorrow", and again, just like the car K.I.T.T., it responds with the correct information. In the above case, the weather for tomorrow based on your current location. If i ask Siri "What THE answer is?", it sometimes responds with the number 42, this is for nerds and geeks a pretty witty answer (as it is THE answer to THE question in Hitchhikers guide to the galaxy). Thus Siri seems to me, have personality, it answers questions with a certain flavor. For me, in 2011, it was the very first time you could ask almost anything to a device (a mobile phone) and it would (try) to give a smart, witty answer.
So is the fact that you are going to talk to your phone and it actually understands what you mean and then responds, something we're going to see more of in the future or is it just a hype?
