The only error I have is 3g not connecting after the update, but that could very well be one of the issues I'm having with my account at the moment. The update is pretty stable. I might have 3g issues, but can't tell because I don't have the money to restart my plan which ended yesterday -_- I don't see many changes. So far the only noticeable change is that Google Magazines is now installed. So far, no consensus. If you can get the update to work after you root, the root does stay. Power off the phone, then hold Vol-Up(Vol-Down?) + Power button.
