Yeah, I'm quite impressed with it! I haven't had any issues, I just did a quick restart after the installation.
It's funny, I've wanted it so badly based on principle, yet not a ton has changed. Little tweaks here and there, but basically the same. I always get frustrated with Android's subpar method of updating the OS (I'm looking at you, manufacturers and carriers), but we're basically at a point where our phones are fairly capable. We aren't behind on major features like we would be 5 years ago.
