[Haskell-beginners] Values vs. Continuations

Hello all, a suspended computation in the Continuation Monad is something you can apply a functio to, right? But this holds for ordinary values as well. In fact, some point out that continuations (acutually suspended computations) are almost indistinguishable from values. If that's the case, can somebody please explain what exactly is gained when we turn everything inside-out to get from values to suspended computations?
