Abstract. We will make a rapid review of results and conjectures about convergence of Birkhoff sums and existence of physical measures for differentiable dynamical systems. Then we consider how some "suspicious" results appear when the same results are applied to systems which are merely continuous. In the generic case, we can give a fairly complete description.
