I have to disagree with you - I got my SGS2 this spring (live in Europe) and it feels quite right to me. Browsing, for one, is really smooth. I thing Samsung did a good job with their Android customizations (well, they copied a lot of features from iPhone).

However the iPhone UI is much more polished. That can hardly be debated, feels to me like the Android dev team "just made it work" and didn't have too much time to worry about polish.

I really hope ICS fixes that.
