As a counterpoint, I'd still prefer MB = 2^20, for this reason:
% dd if=<file/device...> of=<...partition/disk> bs=1024 count=16384
There are still too many other devices out there that still use 2^10, 2^20, etc. for kB, MB, etc. for me to want to change reported sizes for disks to something scientific. Given the 2^x definition of prefixes it's easy to determine what the above parameters for bs, count should be. With the 10^x definition it'd be more complex.
