An interesting question Bob, that made me re-consider a few issues-
putting aside the reality of OpSec being part an integral, but often
ignored (except when it comes to apportioning blame) of System
Security[*1] - an *abacus*. Seriously.
AFAIK it's the only working, perfect integrity shell, on verifiably
trustable hardware. Of course it won't do Fffacebook... :)

After more consideration on that question (and I stand by my original
answer). Based on my experience the court often wrongly concedes that

[*1] security being an end-to-end problem, *if* the "secure" computer is
in a perfectly secure environment and never connected to a network, the
biggest problem is the meatbag sitting at both ends. What people seem to
want is a "simple solution" that's "usable". Firstly simple is a synonym
for dumb, and secondly "usable" generally means "not do-able" without
compromising security (too many eggs in one basket being common).
Unrealistic expectations are the predictable accompaniment of magic
boxes - and serious risk management would ban most of the activities the
average "user" wants a "secure" system for.
