It is not even a prefix.

In computing the "K" stands for "kilobyte", not "kilo" + "byte", and a 
kilobyte has always been the number of memory locations addressable by 
the A0-A9 bits on the address bus of a bytewide system... that's 1024 
possible addresses, not 1000.

IOW, it is not just shorthand for an enumeration (as the SI prefixes 
are) or a mathematical constant, it is the name of a physical constant.

"Kilobytes" naturally became the measure of capacity, (sadly) it may 
also be natural that Marketing twisted its ambiguity with the SI prefix 
in an attempt to get marketshare.

"1024" will go away when we stop using binary computers. :)
