The nice thing about LUKS for the end-user, however, is that it's well-supported in most Linux distros these days, and the end-user can turn it on within the graphical installer literally by checking a box, "Encrypt my Hard-drive."

When ZFS gets there, I will probably switch to it. Until then, however, I find manually partitioning volumes on the command-line to be terrifying, and I imagine I'm not alone.
