Well, Tails comes to mind, they use mostly free software (although I admit
they might have drivers in the kernel, I am not positive about this), and
have privacy as the main strenght.
The reason why I don't use Tails, is actually the reason that makes it so
good as a private OS:
-No way to access internet without Tor (in a safe way at least, even if non
private);
-Outdated apps like openoffice and such. It's based on old debian so that is
to be expected.
I chose to use a non compromised system (I try to make Trisquel into a non
compromised system as much as I can) and privacy tools like Tor and OTR.
