The problem with FAT is that it's so ubiquitously supported, so any
alternative would destroy the value in existing implementations. This
is bad news for FAT alternatives, because damn near *everything* reads
FAT. My HP-49 calculator, GPS devices, your BIOS's page 0 recovery
code, camcorders, cell phones, you name it.
Lots of these are embedded devices, and embedded engineers have to be
very conservative in their design decisions. With billions of these
things being made every year, there would have to be a very good
reason to switch to an alternative. Since extensions to FAT like
TFAT, exFAT, and Sandisk/M-systems's surefs all add support for
poweroff-proof transactions, the only motivation I can think of would
be Microsoft demanding higher license fees for FAT implementations.

I have no doubt that it is a part of the destiny of the human race,
in its gradual improvement, to leave off eating animals.
