They almost always mean power of 10, unless you're discussing RAM, RAM addressing, or RAM pages. (or flash, which has inherited most of the same for most of the same reasons)
Nice page, and nice link to Colin Percival's page too! Let me toss you one example: CDs are marketed in mebibytes. A "650 MB" burnable CD is actually 650 MiB ≈ 682 MB, and likewise for "700 MB" being actually 700 MiB ≈ 734 MB. DVD and BD do use metric prefixes correctly, like you pointed out. Back in the day, I archived my data on CD/DVD/BD, and I planned out my disc burns to have only about 1 to 10 MB of wasted space, so I had to be very aware of the true definition and exactly how much capacity was available for me to use.
