Ah, sorry.  Too early in the morning it was.  :-)  But the point's still
valid.  If you send your outgoing email encrypted to you also, then if
your key is ever compromised in the future, all your past email may be
revealed.

It's easy to re-encrypt a partition with a new key, even quite often. 
The equivalent operation with PGP would be to take every PGP-encrypted
message you can find encrypted to your old key, decrypt the messages,
re-encrypt them with your new key, delete your old key, and hope you
didn't miss any.
