Well, to nitpick, they say it correctly, as for their "kilo", 10^3 bytes is
correct. We, the binary folk, assert kilo to be 2^10 bytes which is actually
called kibi, but we still use "kilo" in our everyday language thanks to
historical ballast (and because, as I recently heard, the -bi units aren't
around that long yet). First time I heard of them was in uni lecture ~2003±1.

By 1.024^4, which is 1.0995 to be precise. Those swines are stealing almost
10% from us. :o)
