>And since any idiot and his brother is a expert on computers, after he managed to find the power switch, there s no help any more. The language is hijacked by marketing. What do you expect? A world where we need extra KiByte for 2^10 to differentiate to KB 10^3, only because some liars figured out they can legally cheat on HDD size. ¯\_(ツ)_/¯ Lately I found a power bank with 10000 MAh. Just like you annihilate the whole thing ....

I vaguely recall seeing an advert (for an 8-bit microcomputer system) back around the late 1970s or early 1980s that stated something along the lines of:
"while our competitors give you 64 kilobytes of memory, our systems are equipped with OVER 65500 bytes of memory."
-- which took advantage of the confusion between the binary and decimal use of "kilo"

The only problem I have with the binary prefixes, kibi-, mebi, gibi, tebi-, etc. is that when you use them, it ends up sounding like you're speaking in Ubbi-Dubbi.
