You may have read it elsewhere, but I'm speaking from personal experience right now when I tell you that Android 4.3 on my 2012 Nexus 7 totally revives this hardware. It's really true what people are saying. This machine now performs as smoothly as the Nexus 4 is famous for doing.
I'm very pleased with the responsiveness upgrade, which people are saying is due to implementation of better memory management. Whatever the cause, my Nexus 7 feels like modern hardware again, and I love it.
