Maybe it's just me or it's just how it works in a typical net environment, but for all practical purposes layer 2 and layer3 switching are the same. Most switches are layer 2, AFAIK. When running TCP/IP, machines on thet network use arp to map the IP to the MAC. Only worth mentioning since recently I did some checking on what Cicso offered with their various models and I couldn't find any reference on the differences between layer 2 and layer 3. Not my money, but paying more for a feature without any details on the benefits... Also gives reason to your comment on the layer 3.
