GPS's have taken over with way more detail then any street atlas could ever have not to mention real time traffic and weather data. I imagine that with the GPS units, Google mapping when in coverage and the magnitude of apps that can be downloaded to any smart phone that atlases just aren't selling anymore.
I would rather have a good paper state map for general overview planning then a GPS or smartphone with loaded maps for actual travel use. Never found much need for an atlas as they usually don't have the off highway back road detail I need.
