Here is my recommendation to you:
Find someone in your area with a Droid, a friend, cousin, joe schmoe you trust...
See if he has the update. Or better yet, manually updated his/her phone. Reason I say this is that when you talk to people about their experience, it will always be 'relative' to their perception. If you are not sure, see for yourself with their phone doing the things you want and compare it to how you do it on your phone, hopefully, with them being on the same level as you are with regards to what apps are running or not running.
I find that when people report 'jerkiness'... It is also a little speculative due to the fact that apps may also introduce a little squirrelliness into the mix or it is a perceived belief.
Point in fact - I have a user who believes the internet is 'slow' because of something internal. And he was right for one part, but when that was fixed, and then something else changed, he went back to that same belief it was 'slow' or there was something wrong. He even went as far to believe that his internet connection was faster than ours (Which physically it was.), but failed to understand how he was measuring the 'speed' because he was using a website loading time as his measure and the fact that a larger pipe does not make a webpage load faster 100% of the time. Other factors play into it.
Suffice it to say, my recommendation is do a comparative against someone else's droid with yours to see if what your concerns are about are going to be issues for you.
