iam a little unsure about the upper/lowwer case and kibibit (every time i read
about these gigibit units i somehow want to vomit ...)

maybe we could have lowwer case for one and upper case for the other
or we just follow all the standard comitees and add kiB, MiB and GiB
after all using k to mean 2 things is just wrong and theres no real standard
which say k=1024 ...

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
