This is the latest official ROM and it's really buggy. At least I couldn't stand it and had a lot of problems with it. I then tried a lot of custom ones and finally I chose ICS Stunner, an Android 4.0.3. It works awesome, it's based on AOKP with all the Euphoria controls and I'm very happy. A downside for some might be that you're stuck with Apex launcher and miss the Samsung Galaxy Note apps for the S-Pen.
