What's the consensus around speed and battery with 2.2?
For me, the speed is roughly 30% faster opening and working with the built-in apps (mail, messages, calendar, etc.). Third party apps are about the same, but I think that has more to do with those particular apps than the watch itself.
As for battery, I'm seeing about a 10% improvement on normal daily wearing.
I agree with all who say the watch is slow overall, but the 2.2 OS noticeably speeds it up for me.
