Possibly Goodbye To Android
Watching the iOS livestream, they're bringing pretty much everything I want to iOS (3rd party keyboards, better sharing options, cross app communication). Unless they stick with a 4" screen once again, I'll be switching when I get my new phone. Google services seem to work just as well on Android and iOS now, so I don't see any reason to stay anymore.
Plus, lets be honest, the home automation product support will be much greater if its anything like 3rd party accessory development in the mobile market right now.
