Since the very sentence I was responding too was about apps ("iOS is stagnant, reviews of recent Apple designed skeuo-heavy apps bemone the lack of functionality") I fail to see how talking about app functionality is some huge leap of logic on my part.
"he was talking about visual design and interaction. None of the things you list here are in that domain"
How is voice control not about interaction?
1 - replaced what they already had and then moved it up to feature parity with the competitors
2 - pioneered it then let it sit, is Siri really that much better and personally assisting me today then at launch?
3 - which appears to be only a response to the competition's great cloud integration
perhaps stagnation is too strong a word... tread-milling perhaps?
(1) Maps is probably the biggest thing they've done since the original phone's launch;
(2) they are moving more and more of the interaction to voice every year;
(3) they are moving more and more of the users' data to the cloud every year.
