Do as Veronica said. If you don't like it, you can always boot into Clockworkmod and restore your backup and be back to where you are now.
Unless you use some of B&N services, like the magazines, IMO there's no reason to stay on the stock OS. Its ****. People here have made it tolerable with various workarounds but its ultimately ****.
Edit: for the love of god though, the first thing you better do in clockworkmod is make a backup and secure that backup somewhere.
