Well, I could see why they used base 10 for magnetic hard drives (since there aren't a power-of-two number of storage spaces available), but what about SSD's, which are best accounted for in base 2? Also, the GPU and ethernet argument is off base (no pun intended); CPU speed (in Hz) is based in units of s^-1, so it wouldn't make any sense to redefine that in base 2. Ethernet speeds should probably have been measured in base 2, but the numbers are so widespread now it would be confusing to change it.
