Not everyone, even in the US, cares about virgin-a55 "smooth" operation characteristics. I wonder if you "stutter" in real life, or could entertain people in a "smooth", eloquent way instead. Or be "lagging" after a boozeful "one-buck-all-night" drinking contest with your flashy poser friends. I just can't keep from laughing over this stupid repeated over-usage of "smooth". Maybe you should start tossing in "elegant" too, North Americans like that in the context of UIs.
