I am starting to notice that every new theme is responsive. So far the only themes I know that the responsive features can be turned off are seydesign and themeflood. If there are others I would like to know. I for one will not build a responsive site unless the client asks for it or his traffic demands it. I would like to see the theme devs offer a non-responsive version of their themes or at least a way to turn it off. I would like to hear what other people here think about this.
