I'll second your point on Android Studio. I was really hoping to see it was getting some serious attention this I/O (but I'm not watching everything live so maybe there is something I haven't seen yet)
As someone who literally started developing for Android about 3 weeks ago, I also share this sentiment. Android Studio (and a pet plugin project a couple old coworkers are working on that makes Maven look downright dumb) and Gradle have been a godsend in getting me up to speed in Android development. I tried Eclipse once in the past to port an old app and absolutely hated everything about it - which I naively ascribed towards the entire Android dev ecosystem as well back then.
I'm hoping for some more stable AS releases and a plan for a 1.0.0 soon.
