There was a recent thread on the linux-kernel mailing list about changing all references to KB, MB, etc. to the new standard KiB, MiB, etc. Some people were for the change, since the new names are unambiguous, while others think it is kind of ridiculous for a third-party to change the definitions that have been accepted for years. I'm in the camp that 1KB of RAM is 1024B, and 1MB of hard drive is 1024*1024B. That's what they've meant for years, and the hard drive manufacturers playing with specs and getting the public thinking 1MB=1000*1024B is not a good reason to change.
