Obviously AI is going to have a pro-Apple opinion on this. At the risk of being called a troll, despite about 95% of my posts being pro-Apple and being here for years etc, this is a very very bad move.
Think the average user. I mentioned something about iOS 6 recently and a non-technical friend replied on Twitter that she was looking forward to it. Shes a big iPhone fan.
What she will get - the most obvious things at least are
1) An inferior map service with no StreetView
2) No youtube.
Whats new? From here - http://hothardware.com/Reviews/Apples-iOS-6-Whats-New-and-Whats-Missing/?page=1 - because I honestly forget.
Siri on iPads.
FaceTime over 3G
An Iphone user wont notice siri on iPads. Reading list is a minor addition. FB integration wont matter, as apps do that already where they need to. Passbook wont be useful off the bat. iCloud integration on Safari is a small update, and matters to people with more than one device. FaceTime, not really used on iPhones and you better never use it on a data plan.
So, the update will seem like a regression to the average user. They will download and wonder what has changed and miss youtube and google maps. The day after a general release the conversation will be how to download google maps and you tube.
This is nuts: just as Apple uses google search, it should use google where it has to, where Google is better. And cut the crap.
