Jelly bean
Looks pretty much the same, a little smoother and mainly little tweaks which are an improvement over ICS. Battery life isn't a concern anyway as its already pretty good and look, let's face it we all have chargers everywhere...work, car, home.....
So all in all I'm pretty happy with it. ..swipe is better than when in ICS to. have fun trying to find where to enable it, haha.
I flashed to the official international version as I couldn't wait and did notice Optus started installing its bloatware as soon as I connected to the market bit they are now removed.
