Bull. Standard and convention is: 1 GB = 2^30 bytes; 1 MB = 2^20
bytes. Hard drive manufacturers *only* (not semiconductor memory
manufacturers!) have recently tried to define 1 GB as either
10^3 * 2^20, 10^6 * 2^10 or 10^9 bytes. This is just silly to go
along with, especially since they can't even make up their minds
(although I suspect most of them are going towards 10^9 since it is
the smallest.)

However, in the memory arena there has never been any doubt that
1 GB = 2^30 bytes and 1 MB = 2^20 bytes. That is the only standard,
the rest is just marketing hype.
