The challenging part, as always will be to understand what percentage of this technology would have been deployed regardless of what Apple did, and whether it would have been deployed with the same attention to detail and quality.
I understand that Droid's are already somewhat voice controlled. Will be interested to see how Apple's implementation compares with that, and the Windows Phone 7 voice control. Anybody have a droid and windows phone 7 that would like to comment on how well it's implemented on those platforms?
One of the examples was: 'Do I need a raincoat today?' and you can continue 'How about tomorrow?' or 'where can I buy one?', and Siri understands the context. This is far far more advanced than any 'voice control' there is, and gives just a glimpse of what's coming.
I tested the current state of voice recognition on Android and was mostly disappointed (bad recognition, and nowhere the "intelligence" you would expect).
Yes, the integrated Siri is going to be better, but is it going to blow your mind and revolutionise the world? No. Get back to me when it can understand a non-Germanic language.
