B.Schneier made a good point about writing passwords:
"People are highly proficient at keeping small sheets of paper safe... 
in their wallets."

Actually, writing a password on paper is much better than transmitting 
it (over what channel?) to a data storage application.
People have tremendously poor control over computer programs. Contrary 
to this, physical tokens (sheets of paper) included are very well 
controlled by humans.

Besides that, trusting your password to a program raises some certain 
"identity issues": You do not authenticate yourself in this case, you 
authenticate a program. I do not want to allow a program potentially 
impersonate myself.
