Using them you can experiment with various settings without changing the set up of your layer structure. In addition, you can edit your artwork, even months or years after finishing it, simply by altering the Adjustment layer or changing the layer effects parameters. For instance, if I decide at some point that don't want drop shadows anymore, I simply click on the layer effect representing the shadow and I turn it off, or add other effect if I want to.
I'm not a PhotoShop user so please excuse the question but how does your example *not* change the setup of the layer structure?
If I add a drop shadow to something in Gimp, the drop shadow is in a layer an I show or hide. How is that different from the "Adjustment layer" you describe? I'm sure it is but I don't know how it differs. :)
