As was the common convention, all advertising materials, all reviews, all documentation and all common understanding was that the 64 in its title represented 64KB as in Kilobytes.

This same convention, for MB = Megabytes, and GB = Gigabytes and all of these representing powers of 2 (no matter how "incorrect" that may be), was proliferated through the overwhelming majority of advertising, commentary and documentation both previously through the 70's, and through the 80's, 90's and 2000's.

This was the convention commonly understood for the many-decades-long duration of the birth of modern computing.

To attempt to change it after decades of intrenchment for the "technically correct" version and gain loads of confusion, and almost nothing in return, is a bad value proposition.

Except when it, of course, isn't. $10M is certainly not ten megadollars.

Even science isn't that consistent about it. The SI base unit for mass is the kilogram. Yet we don't have megakilograms. We have megagrams, but nobody uses them. Instead we use tons. Somehow kilotons and megatons are used though.

If we're willing to accept the above then why couldn't we have stuck with the powers of 2? Digital information at some level is going to become base 2.
