Its a generic/maintainable way of programming.  It means you can change 
the types your using without having to change ever reference to it.  It 
means you can copy paste or template a piece of code and have it work 
with little change.

It gets even more useful in larger programs when you start to layer this 
sort of general programming.

I hope that helps.
