The space shuttle tossed most of the hardware and required a billion dollars of refurb between flights, I've heard it called a 100Ton payload fairing. ;-)

Yes, STS is a hard one to pigeonhole in terms of flight regimes. They ditch the LOX/H2 tankage, which is a bit like throwing an apartment building away on every launch.

They did recover the SRBs, a useful fraction of the time. How often were SRBs actually reusable? Anyone have stats?

But the Shuttle itself, yeah, is payload that comes back.

I think a boost-back scheme, that SpaceX has successfully demonstrated tonight, is in a noticeably-different category, and one that deserves
much celebration, even in the context of historical machines like STS.

For some reason the Space Shuttle just didn't seem as real to me as
this. I put it right up there with Niel landing on the moon. I'm not
even sure why it feels that good.

That felt GOOD!
