I got tired of the wait for 2.2 and just downloaded the update.zip file last night on my phone and my wife's MotoDroid. Only issue I had was anti-virus and GPR Tracker apps went bonkers when the phone was restarted, so I uninstalled/reinstalled after the reboot and they've been working fine since.
I'm very happy w/2.2.
