Typically it goes like this:

(a) People who have problems complain here.
(b) People who don't have problems, won't say anything.

So you'll only observe those who have problems.

Personally, I haven't seen any new major bugs in PR1.2. I'd say go for it, it's supposed to be better than the old one.

As for Nokia being aware, I'd say yes. But software that has changing requirements will never be complete, and they had to release it already. There was a dangerous amount of pressure being built up in people's heads around here, they might have started to pop in another two weeks.
