While you can achieve very similar things with both abstract classes and interfaces, the crucial difference for me is that an interface can only define the contract whereas an abstract class can not only define a contract, but can also implement some or all of the contract.

My personal preference is to use interfaces to reduce the coupling of dependencies in my application. I tend to use abstract classes when I need a base of shared functionality that I can inherit and derive other more complex or specific classes from.
