Encrypting a filesystem is useful if you loose your 
laptop/flashkey, when you aren't around when the people find 
your harddisk. However an encrypted filesystem is useless 
going through TSA/DHS when they can just say "give us the 
passwd or you're going to Gitmo". In this case you need 
plausible deniability - "what encrypted filesystem? there's 
no encrypted filesystem, that's just random deleted files". 
I notice that you can have plausible deniability, but as you 
would expect it's proportionately more difficult to setup.
