A simple cosmology with slowly growing Newton's coupling
constant motivated from Brans-Dicke coupling theory and
decaying vacuum energy density in universe with flat
spatial curvature is considered. Despite the simplicity
of the model, it exhibits interesting late-time dynamics
consequences in agreement with recent observations.
