I just took a chance and updated. Like all updates, first startup was slow and laggy. Did a reset with the power button and volume down button then booted it back up. Ran much better. I used Voodoo rootkeeper to restore root. Had some issues with titanium backup but other apps that required root worked fine. After a reboot, fired up Ti backup and it updated SU binary files and it was good to go. I did another reboot and EVERYTHING messed up. Every app had force close issue. Did a hard reboot and it booted back up fine.
Seems a bit snappier. Quadrant reported around the 2600-2700 score range. Before it was around 2500-2600. Not too much of a jump in terms of scores but overall feeling and usage of the phone seems snappier.
