I have a Sony Vaio latptop of simiar spec. to the one you mention (2 
GHz, Centrino, single core) and I have after comparing it with the 
current equivalent model (which we sell - and which is Dual Core) not 
found it worth while to change it before its end of life.

In normal laptop use, having an extra core will make little difference. 
  There are areas where it helps: primarily (surprise) multi-tasking, 
which I find most evident when switching to another application while 
leaving some procedure to complete. A dual or more core machine is more 
responsive in the user interface when loaded.

On the other hand, the difference is not huge.

There *are* some big advantages to the recent multiple-core laptop 
machines, as follows:

- capability to run 64-bit code and so efficiently use more than 3.5 GB 
or so of RAM

- full hardware Virtual Machine support so better capacity to run these

- better power efficiency
