True. But as I _am_ a nerd, I wouldn't really care :-)

:) Not for me, ... as I was (roughly) refering to the time I have been
programming/using computers.

I see your point, but I still have a different point of view. 'k'/"kilo"
has been used for a time much longer as being 10^3, then the recent
years were it had gotten popular in the computerworld to use it meaning

So, still I think, that chosing a naming and giving it an _almost but
not exactly the same_ value is not a good thing to do.

In case of the mouse, I do not really see a problem; as they are
_truly_ different things, I think confusion will not be a problem
to really worry about.

In case of the typewriter... that's a bit more annoying. But, as
typrewriters are clearly deprecated ;-) the problem will fade away.

You can't say that about k==1000 :-)

In fact, I know a few of people who did find this confusing.

Sure, in human language it is important. A lot of humor would be
impossible without it. But for units, I still think it is wiser to avoid
