Fire up iTunes, hit the Update button, and BOOM! 2.0.1 is live and in prime time. Actually, in 250MB of what Apple's always super-verbose product details says "includes: big fixes".
I'm downloading it as I type this, but Engadget's already gotten their mitts on it, and say things feel snappier.
Have you gotten it yet? Getting it now? Gonna wait and look for error reports first?
Whenever you get your 2.0.1 on, please drop us a note and let us know how it's working (or not!) for you.
And Apple -- thanks much! Now about that 2.1...
