Has anyone not installed the latest update?

I haven't installed it. I don't seem to have any real issues with battery life or WiFi, and I"m not willing to give up using Unrevoked and WiFi tether. Oh, and Titanium Backup and the full capabilities of MyBackup, either.
 
exact same as the two above! Once I get some time to look into the new rooting options, that will be my next play!
 
I only have launch day OTA. In a couple weeks, I will check into the latest roms, things should be fairly mature and smooth.
