How will the migration from WS2003 benefit businesses beyond the simply regaining Microsoft support?

What are some of the potential indirect benefits of moving away from Windows Server 2003 as it reaches end of life? I’m thinking of things such as decreased expenditures or improved security….is this likely?
Making the case for upgrading from Server 2003

"For some, the pain of upgrades lies in the legwork of testing and certification of the new operating system, getting apps ported and training admins on the new administrative interfaces.

The jump from Server 2003 to Server 2012 is a big one. RSAT 2012 is a real break from previous iterations and PowerShell opens a whole new world of administrative possibility that Server 2003 admins rarely touched.

For others, the pain comes from the amount of political capital you have to burn to get the funding unlocked. I feel your pain; I face some massive Server 2003 migrations over the next few years."
Well if you are running WS2003 servers they are likely very old and not very power efficient. So new servers will be more modern and use less power, and likely much more powerful.

WS2003 is a 32-bit OS while Server 2008 and 2012 are 64-bit, so you can run a server with more than 4GB of memory, which means a much higher load can be put on the server. You can virtualize, consolidating many single-purpose physical Server 2003 machines into one physical machine.

The security in Server 2008 and 2012 is also considerably improved. In Server 2003, once someone breaks through your security they have pretty much free reign to run amok in the server. WS2008 and 2012 are more walled off internally, so a break in to one area won't necessarily grant them access anywhere else.
