Based on theory and experiments in weakly interacting electron systems, it was believed for many years that no metallic phase is possible in two dimensions. The unexpected observation of metallic-like behavior in strongly interacting electron systems has thus drawn considerable attention. Following background material and a brief history, we review the dramatic response of these 2D systems to in-plane magnetic fields, and the evidence this provides for a possible quantum phase transition.
