Nothing wrong with a filesystem (or apps) that can handle being powered
down.
But I prefer to handle this kind of users with a power switch that
merely
acts as a "shutdown button" instead of actually killing power.
The os will then run the equivalent of "shutdown -h now"
You may not have this luxury on an ordinary pc, but you do if you design
embedded
devices. You will then be free to use existing GPL software that
not necessarily handle a power failure well.
