What you're really seeing here is the limitation of full disk encryption. I talked a little about this here (the article is really about cipher modes, though):
The problem isn't "crypto". The problem is the extent to which full disk encryption overpromises and way, way underdelivers. It's easy to have a cryptosystem that is at least somewhat resilient to this threat. You just can't get it with a UX that "unlocks" your whole computer to use it, and then "locks" it again when it goes idle.
The problem of evil maid attacks is at least trying to be addressed by the QubeOS team, and think it's an interesting concept. Otherwise, yes, FDE is only a part of what should be a holistic approach.
