I'd see it as a very positive sign : Nokia has bosses who are capable of understanding that if they rush the QA cycle and push out a half baked product, then the real bosses - the customers - will burn them at the stake.
If you cared to read the content of that blog, it seems that they aren't just interested in pushing new features. They want us to be able to use the phone for long periods of time without needing a reboot.
They're also doing performance testing to ensure that the speed of the device remains consistent over an uptime of a week or more.
From a stability and performance point of view, that means Nokia is pushing PR1.2 towards the level of stability I've experienced in other smartphones.

I'm pretty certain you'd want your phone to be stable and fast to show off to your iPhony, beebee and goog-phony friends.

For now, relax and enjoy the summer. Have a mai-tai!
