I'd say that 2012 is very stable. I haven't used it extensively (using 2011 SP1 for current projects), but it is a whole lot better than 2009 was for me. I did some devolopment with the Beta. I was supposed to be developing with 2009, but it kept crashing on me and I had all kinds of bad luck. I used the 2012 Beta and had only a couple of minor issues (it was Beta after all) and back saved to 2009.

I think the posters question is totally relevant. Like many other companies, NI has occasionally released "unstable" software with an unsatisfactory number of bugs. The first version of LV DSC is a good example.
This appears to have changed in the past 2 years at NI, and their software is far more reliable. The general consesus is that LV2012 is quite stable.
