Has anyone tried it yet? I'm about to flash my Nexus 7 tablet up, but I wanted to know if anyone had seen any of the new features etc.

I'm running it on both my Nexus 5 and Nexus 7. Its great on the N5, but its a bit choppy on the N7. From my perspective, there's aren't any major new features that caught my eye, but all in all, the whole interface seems more polished.

I only have 11.2 GB free on my 32GB tablet. I think something went wrong there. Going to reflash to a stock image and retry. It wasn't choppy at all on my Nexus 7 (2nd Gen) but I expect to have to replace it fairly soon.
