I've had several machines running ext4 or other journaling filesytems
survive major power failures without as much as a blink. That's the
point of having a journaling file system. Coherency is always
maintained. ZFS handles that also quite well...


Now if your filesystem is not fully supported (btrfs) or not
journalized, then this is another story.

I don't control the OS on which my key applications are made
available... both for work (my employer provides my machine) and for my
photography work (try running DxO on Linux). Actually for work, I moved
the original Windows partition to a VMDK file, installed Ubuntu, and run
Windows in VBox (I still need Windows to authenticate to the corporate
environment).

And I use a payed version of Avast. Why do you make the assumption that
it is free?
