Why bother with BSP???

Howdy,

I'm an ABAP programmer and I can't understand what is the benefit of creating BSP pages?

Aren't they just a way of displaying a report in a web-browser, rahter than in SAP? If so, what is the big deal with that?

Why should our company use BSPs is probably the question that I am trying to ask and is there much f a future for it? For unlike JAVA or ABAP, BSPs are not core SAP technology, are they???
