I believe the following:
If you get the update now, you will be depressed later, at least until the rumoured 2.1 release in January, at which time you may perk up again.
State at your Droid, try to make it grab the update notification by pure force of will. You will lose, the Droid cannot be pushed.
The lock screen; well, I thought the "wheel" implementation was nice, but can live witht he new one as well. If you own a Droid, you should be open to change!
The new widget look: Awesome, yet still functional, goes better with the overall look of the phone (cmon, white power widget??)
I'm staring at mine in the dock, waiting, but happy with it so far in its first week.
I'm also sure 2.1 will have its pluses and create a few minuses when released as well, but lets remember, that is not an update, but a revision of the OS, should have more pluses than minuses in its corner... you know, every odd release ....
Ohm yeah, hasnt happened yet, and it is my birthday, cmon droid, give me my present!
