I'm like you..sitting at .167, and debating whether to upgrade. If you check via phone, it says no upgrades available.
Other than battery life, as you mention, and non-software issues (like the weak vibrate), I'm reasonably happy. I may have a slight uptick in dropped calls in weak areas compared to my 8700, but it is tolerable.
My bet is, the feedback will sit about 50/50, so its a flip of a coin..
