Yes, this all started when some ignorant computer people thought that 1024 is 'nearly' 1000 (kilo) and therefore began to call 1024
byte a kilo byte. Not only that these both notations are meanwhile departing more and more (starting with 2,4% deviation for kilo,
then 4,8% for Mega, 7,3% for Giga and already 10% for Tera byte) there where even mixed notations (floppy size)!
What also confuses is that when the same number of bytes is indicated with different prefixes in base 2 notation the numbers can
look very different. For example, 1012 Mega byte would not be 1.012 Giga byte but only 0,988! That's ridiculous!

Yes, I fully agree.
