I am in the process of switching from PC to the Mac.
On the PC I use PGP virtual drives - you know where you enter a passphrase and it mounts a volume and on shut down, that volume becomes just one encrypted file until next time. (I tried whole disk encryption but too many problems with it, to justify it for my less than completely robust privacy needs)
Now I see on the Mac you also get PGP (http://eu.store.pgp.com/desktop_pro_mac.html) but I seem to recall other products and also the possibility that the technology is already built into Leopard?
