Sorry - I got twisted up there while rephrasing and retyping things.

The *box* should not say 2 GB - that is a bug, but I don't usually
know where to report it :)

I'd suggest software would want to report it as 2 GiB.  Saying 2.1 GB
will probably confuse users more than saying 2 GiB, and thus may be a
bug, though the context could make a big difference in all that.
