* 1. What sort of problems (if any) did you encounter with the design & development process creating a fully responsive website?

* 2. Have you worked on a project which actively chose to run a "mobile" site as well as a desktop site instead of a fully responsive single site? If yes, what were the reasons behind that decision?

* 3. When working with an existing "fixed desktop" website which is being updated to be responsive, what do you do with existing templates and content? A full greenfield rebuild or reverse engineer existing code?

* 4. Do your responsive projects require larger budgets than older style fixed layout sites or have you been able to make savings elsewhere - eg: quicker prototyping/design in browser etc?
