Could be anything. cameras, phones, etc. Anything that might be
mountable by a host computer in order to share files, or to write to a
device that can be shared by other computers or devices.

An example, an mp3 player wants to read files with long mixed-case
names, which can be manipulated on a host computer. But it may not need
to create files that don't fit the 8.3 syntax.

Of course, msdos might be a good option for other devices.
