What's the purpose of running Armory through Tor? What's the purpose of running Armory through Tor?  Is it only useful once you get to the point where you start sending Bitcoins?
Armory (in online mode) uses a full node.  Full nodes relay transactions for other programs on the Bitcoin network, so by running Armory on Tor, you help other people send their transactions with possibly-improved privacy.
Sending your own transactions through Tor with Armory can help prevent anyone from associating your IP address with your transaction, possibly improving your privacy.


Note: Tor and Armory must both be used properly to achieve improved privacy.
