apple were the first company to produce a voice activated affordable desktop computer with the quadra 840av , i had one and it worked really quite well - for very basic stuff

i don't see the point of it in an audio/visual product as no doubt if you're listening to either a spoken word recording or god help us rap , the thing would probably self destruct at all the conflicting commands

While I am a fan of the iphone... and nothing else.. other than the laptops..  I think apple may too find themselves looking for thier mojo as thier ideas will run dry and become dare I say boring and repetitive and in the same position as B&O.
