Jelly Bean Emulator

So jealous people who got Nexus 7 and Nexus Q at Google I/O ... I really hope I could be there one day. Whatever, Today I just updated Android SDK and the Jelly Bean (Android 4.1)  was here. I run it on emulator. From my point of view, It's look pretty much the same with Ice cream but they said it was a lot of improving performance. May I need a real device to prove it.

Upgraded to Android 4.0.4

Nothing, Just want to show you that my Galaxy Nexus was upgraded to Android 4.0.4 without problem (At least for now... )
