Yes, I would add Tamper Evident.  I don't want to carry a key management
device everywhere.  It _might_ be feasible if it was one of those stub usbs
that are as small as the plug itself... but there goes the display.

The question is, can tamper evident be grafted _onto_ a kindle easily and
reliably?  Nearly all forms of tamper evidence have fallen to Defcon's
Tamper Evident contest.  That doesn't mean they're worthless, because they
increase attacker cost, but they can't be relied on fully.
