Device manufacturers use whatever makes the disk appear bigger,
thus it's not an argument.

Most disks have 512 bytes/sector. Which doesn't prove anything :)

I developped a product which gives the capacity of the disk.
It does so by using 1024 bytes for a k, 1024*1024 for a M,
1024*1024*1024 for a G.
Personnally, for everything which is computer-storage-related (memory,
harddisk, etc), I use 1024. For everything else (telecommunication,
etc), I use 1000.
I know it's stupid, since the SI (International Unity Standard) says
it should be 1000.
But don't forget that even in its standard domain, the SI is not
applied to half of the world (in term of economic power: the USA)
for unities.
