Please stop stating this as though it were a fact.  At best, it is
disputed.  At worst, it has become a matter of opinion.

That's certainly not what it means to me, and it does not follow what
the "kilo-", "mega-", "giga-", etc. prefixes are commonly understood
to mean in all other contexts.

Nor does it mean what the IEEE, SI units, etc. define it to mean.  The
IEEE is, in fact, pretty clear that "kilo" = 1,000, "mega" =
1,000,000, etc. now that the binary units have been standardized by
the IEC.  (see: http://physics.nist.gov/cuu/Units/binary.html )

Except it is NOT a new unit.  It is correcting a mistake that was made
decades ago and propagated by lazy software developers.

Unfortunately, the meaning of the *B units has become sufficiently
diluted to the point where we now have two equally-passionate groups
of people arguing over what they mean, and for all the messages that
have flown back and forth, we are no closer to agreement.  If
anything, the two sides have become entrenched and I don't see how
further discussion will get us closer to an answer.

Given the above, I've changed my mind -- I no longer think KDE should
have any units other than the *iB units.  Those are the only units we
seem to be able to agree on.  The meaning of the *B units has been
sufficiently diluted to the point that NO MATTER what definition we
pick, someone will likely misinterpret them.

I think we already have too many units.  KDE really *would* be doing
something unprecedented with this, as it really does break with what
everyone else is doing (nevermind the standards).  You objected before
to confusing users with KB = 1000 -- I think this would be an even
worse source of confusion.

We need to disambiguate the existing units, not make up new ones.
That's why "KiB" et al were created in the first place.
