I always wonder if it is better to just leave sites as unresponsive if you've already skipped designing for mobile. Honestly vanilla non-responsive sites, without too many bells and whistles (hover/flash stuff) are easier to navigate than a poor mobile site (or even a mediocre one). I know what to expect when I click something, and even if I have to zoom in on my own, I still would rather have the actions be consistent with the desktop version than be poking around looking for the menu.
