Rosetta Stone

Anyone ever used Rosetta Stone to learn a language?

I don't really get how it works. It seems to just throw random stuff at you and then you pretty much guess. Is there an actual method or what?

English is my native language. I tried to use RS to learn Japanese and quickly got bored because I felt like it was throwing crap at me randomly.

That said, I think that as a supplement to learning a language it could be quite beneficial. Using it exclusively to learn a language might prove difficult.. or for me it did.
