Finally! Other people who get this! The happenstance of evolution leaving most of us with ten fingers / ten toes is no basis for a system of mathematics. We were doing alright with this and then the bad at arithmetic mob ganged up and got decimalisation foisted upon us.
1,000B = 1GB is the other one that drives me nuts. People to whom it made no difference at all what a 40GB drive meant so long as they could still say it was more GB for their £'s compared to a different HD they were considering, got whipped up by marketing departments to try and change definitions that didn't confuse a single soul who actually needed to work with these numbers and meant endless conversions whenever we did. Raise it and you get dogmatic waving of SI prefixes. Consistency - a tool to smart people and a crutch to stupid ones.
