With Jelly Bean (on at least one of my tablets) i must admit i'm impressed. they finally knocked the UI speed problem (only took them three years, Apple has had it since 2008) but i must admit that it still feels like it plays catchup to Apple. there are also some games that are not ported to Android yet. there's a Star Trek theme, and the Sky Gamblers games seem to not exist yet on Android. for those, i still fall back to my iPad. in my opinion it does have more catching up to do. the same app on Android (let's use Facebook for example) seems like a watered down secondhand copy compared with the app on iOS.
