What are some threats against which OpenPGP smartcards are useful?

Dude, the lab I worked in *required* me to use 128-bit secure 
passphrases.  It was *awful*.  And a 180-day change policy.  But the 
good news is that once you prove to yourself you can do that, the idea 
of keeping a 128-bit passphrase on your certificate no longer seems so 
crazy.

To quote the movie _Men in Black_, "Give it a few months.  You'll get 
used to it, or you'll have a psychotic episode."
