We've been running the 2.0.1 OS update for a few days now and our advice is to go for it. Install the update only once you have a full and complete backup though.
We've had fairly good luck with the update -- even though we've just had our 4th restore, 2.0.1 seems a little faster if not more stable.
The install was quick and painless -- much quicker than the restore process (3+ hours in our case). Let us know your thoughts.
