People always want new vs. stable. I guess forums with stable software are boring. Also it creates conditions to **** about upgrade pricing compared to what's in it.
Angry issues - Live 9's browser. See the multi page rant on that.
Reason 8 - rant never ending. Upgrade should have been a point release. Giving away free stuff to new users that loyal users have to pay for. (you won't see that happen often with Sonar)
Sometimes be careful for what you wish for. At least with Sonar it doesn't over write your previous versions. That's a plus.
Keep in mind most early releases of software will have bugs.
