Just got the update on my Droid. Waiting for the wife's phone to update but it hasn't yet.
Love the fact I can tether via USB now, and I know the newer android phones can be a WiFi hotspot.
Haven't tested flash yet, but I've also heard that may not be included.

I've had Android 2.2 since it was first pushed out to the Nexus One and developers got it working on the Droid. I've had Flash since then too.
