I have always marveled at the way samsung does business but i never dwell deep into it. With magnificent hardware and resources available, i still am unable to justify the reasoning behind each launch. If your tagline has always been something for everyone, then you are by far lacking at it.
I've often been amazed by them periodically and though that sense of exhilaration, it was something that could not last nor lust. With the launch of the latest product that you have, you might have done just the exact same as what you did with all the previous galaxy range. You have impressed but not made emotions.

I like the SGS 2, but i do not love it. To me, it is just another piece of smartphone that is dispensable and ready to be relinquished from its position.

Between the Sensation and the i9100, i'd pick the Sensation only if they rectify some issues which they are highly unlikely to do so. Therefore, having said all that, the bottomline for me will still be the i9100.
