Espionage 3 in a Filevault world

[xco]

Why would I use Espionage 3.0 if I now use Filevault regularly on all my Macs?

What are the advantages vs disadvantages of doing so?

Some reasons could include:

• Espionage 3 adds an added layer of protection on top of FileVault. If your FileVault password is cracked, or you're forced to give it up, then all of your files are exposed.
• You can give your computer to a friend to use without worrying that they'll be able to access certain files
• You can sync your encrypted data with Dropbox between computers.
• Some users have multiple user accounts and want users to be able to use the machine without knowing the FileVault password

I can't think of any disadvantages.
