It will be a decade or three before we know if this shakes out the way that ISO is trying to force on people. The simple fact is that GB has been used for a binary number for decades, just as MB and KB, and the moved from MB = 2^20 to MB = 1,000,000 was driven by Hard drive manufacturers who wanted to market their 100MB drives as 104MB to fool people into thinking the drives were larger than they were.

2^30 is a far more useful number when dealing with computers than 1,000,000,000, which is why many MANY people still used 'GB' to mean 2^30.

But yes, you are technically correct, but that is the worst type of correct.
