in comparison to beta 1 I find this to be marginally more stable, I am no longer experiencing the frustrations for attempting to use an unfinished product in real world scenarios. the phone app once again works, Safari no longer crashes for me, some of my app weren't working at first, but deleting & re-downloading them made them work. I am testing out my my in house business apps and this beta is definitely better.
+1
This is my experience as well.
