You are forgetting a very important fact. Computers use units
that are powers of 2 and multiples of powers of 2. So the
people that know what they are talking about can represent
the memory capacity of a typical computer as 32MB and they
are exactly correct. These people that don't have a clue
would have to write 33.554432MB.

Have you thought about that the output of 'df' and 'du' and 'ls -l'
would look like if they reported in units of 500 bytes?!?! ...or
what the code would looke like if it actually dealt with space
in units of 100, 500, 1000, etc. bytes?!?! Then there would be that
leftover part unit at the end of it because powers of 10 just don't
fit in a computer.

Some of you guys are just not living in reality!
