I too downloaded it...my first impression is the pages load very fast, but that excitement turns to torture when you try to scroll around...it is very slow, almost like it is tracking on a grid instead of free flowing. Also, another annoying part is the back button...this button is just as important as the Blackberry key or the roller ball and it simply does nothing in this app.
I was able to get in and navigate Pinstack without any errors.
Very promising but still needs some work before I will dump Opera Mini.
