I got my update last night as well. I live in the Los Angeles area. The upgrade took longer than usual, but once it was back up, it seems pretty normal in terms of responsiveness. I haven't done a factory reset since jellybean and let it update OTA through till now. Keeping it as stock as can be these days. The only "problem" i had is that i was using the email app before the update and had disabled the gmail app, and google has disabled the mail app in the update and put a link to gmail where mail used to be. The link was busted because I had gmail disabled. Ha. So my bad. I don't think I like gmail as much as the old email app, but it does appear to be working fine.
