I wait until I see the usual progression of posts related to beta OSs:
-15 that say, "it's way faster"
-15 that say, "it's slower"
-15 that say, "battery life is great!"
-15 that say, "my battery is dying in one hour with this update"
-15 that say, "voice quality is much better"
-15 that say, "voice sounds horrible."
After that, I'll flip a coin...
