The (ab)use of the SI multipliers K, M and G to mean a 1024-based value in describing computer memory size started LONG before the hard-disk industry started pushing 1000-based numbers, likely to make their disks look larger than they actually were.

This mess could also have been cleaned up by creating a unique name for the new "true SI" multiplier based values instead of changing the meaning of the old one, as right now you have no idea what you're looking at unless you examine the code, as it will depend on when the app was written, whether the developers know about GB vs. GiB and whether they care to followed the new scheme.

And 1.44MB floppies where neither 1.44MB nor 1.44MiB.  They were 1440KiB
of course.  So 1.44*1000*1024 was correct.  Don't have any unit that's
right for that though.

So common use and history doesn't help much either.

I don't personally mind GiB very much, but I refuse to call them
gibibytes.  What a stupid name.
