Updated mine yesterday from the leaked HTC file. It's fast, very fast. High 30s low 40s Linpack score. Flash is awesome, I have it set to load on demand so only running it when I want. Chrome to phone is cool but doubt I will use it much, waiting on the full media cloud sharing. Had some issues with my apps not showing up on the market, but fixed itself after a few reboots. Battery seems to take much longer to charge but also lasts longer. I did lose my root which I am sure a new root method will come along soon.
Flashed it from the .zip file at XDA-Developers. I was able to maintain root, working great!
