::I've been working in computers since 1980 at the industry level. Kilobytes are KB, Megabytes are MB, Gigabytes are GB, Terabytes are TB, etc. I've never been in any computer firm, be it a game developer, IBM, Apple, a movie company, or a technology company, that uses "MiB" or anything that kooky. In fact, my computer science professors will, in the classes I've taken, outright mark the paper a failure if anything but MB is used. Also, Kilobit, Megabit, Gigabit, etc. are as such- Kb Mb Gb, etc. The only place this "MiB" junk is used in in Wikipedia.
