Although this is a good thing, we really need applications that are multi-threaded and can utilize additional cores at their best efficiency. Since the launch of dual core CPUs, we have been witnessing an increase in the number of multi-threaded applications- especially with 3D Workstation and Video Rendering applications. However the soon to be released Vista Operating system along with the new Microsoft Office 2007 supposedly makes much better use of multi-threading as well. On the Mac side, OS-X is already multi-threaded and the upcoming 10.5 (Leopard) should make it even better in this regard.
