While other answers have already gone into beautiful detail concerning the nature of both units, the most *practical* reason for actually using one over the other, specifically MiB over MB, is simple: At this point in time it is **unambiguous**.

With MB you can never be sure whether or not the user or application refers to 1000×1000 Byte or 1024×1024 Byte because the unit is used inconsistently.

With MiB you know exactly what to expect.
