pathetic update in my opinion, i know i'll get downvoted for that but i'll give you my reason.
all those "incredible" new features are just partnerships with other big companies and thats not what apple used to stand for. such a sell out
Yelp Yelp Yelp, Facebook, Twitter, did i mention Yelp? and Airlines
... SAD
it shows with those new siri commands "where does the movie xy play?" "heres a list of theaters ... by YELP" seriously, thats what they could come up with after all those months?
how about implementing something thats actually useful to the USER like lets say "siri turn off wifi"
those features are also too focused on the US because you guessed it those "partnerships" and omg a "wallet app" like there arent tons like this already at the app store
and still no notification center api for the devs .... the not center looks just SAD and empty on the iPad.
this whole thing reminds me of Mark Zuckerberg and Facebook: "you are a customer and you can connect with people" which translates to "you are our product and we sell you to other companies"
those new features (id rather call them "improvements") on iOS6 are simply a platform to "sell" and just wrapped around and covered up nicely (again, a "like button" at the appstore proves this)
