Another important reason for not presenting the phone's built-in flash
as a USB mass storage device is that it requires you to use a
brain-dead broken-as-designed Microsoft filesystem left over from the
days of 360K floppy disk drives -- otherwise Windows won't know what
to do with it.

It's _possible_ to build an Android phone tht runs an DOS file system
(and IIRC people have done it) but it introduces all sorts of
security, reliability, and performance problems.
