I don't want to continue the bikeshedding but I just want to recall a
point that, as far as I can see, got lost in the discussion.

The point is that:

1 KiB is 2.4% more than 1 kB
1 MiB is 4.9% more than 1 MB
1 GiB is 7.4% more than 1 GB
1 TiB is 10.0% more than 1 TB
1 PiB is 12.6% more than 1 PB

The whole "1024 is close enough to 1000" thing dates back when people
were only dealing with kilobytes. If people had been dealing with
terabytes at that time, they probably would never had adopted that
terminology, because a 10% difference matters to many more people than
a 2.4% difference does.

I'm just saying that even though the current approach of KDE may seem
overly strict at the expense of familiarity to the user, in the long
term it is the only solution, and the rest of software will eventually
have to do the same.

This isn't an argument against Michael's patch that may be useful to
users today, i just wanted to get this point through.

Cheers,
Benoit
