If a device can routes then it is a router. So, you can call Layer-3 Switch as a Switch with Routing Capabilities.
As per my understanding the name Layer-3 Switch is nothing but a marketing term.
Okay, now lets move on to the differences between a Layer-3 Switch and a Router.
A Router can support traditional WAN Links like E1/T1/DS3 over POS interface/ Smart Serial Interface for V.35 etc. whereas Switch can only supports WAN link if it is Ethernet or Fiber Drop.
Modular Switches can support FWSM or ASA Module even Wi-Fi Controllers also.
Again, in compare Router can support Cisco Call Manager Express or ISR G2 routers can support WAVE even.
Usually switches do not support NAT/Netflow or Nbar until you go into a high end Switch like 6500, whereas even small routers can support the same, it is probably because of Router's rugged IOS.
The forwarding on switches is done on ASIC (Application Specific Integrated Circuits) which is done in hardware rather than a software whereas forwarding on routers are done on software.
Now, these all are technical but at the end of the day you need to decide the positioning according to your business requirement because both will provide you the exit gateway.
Good Luck Guys........I will again come back with some post.
