I’d love to hear from anyone using whole disk encryption. I’m carrying enough private data on my laptop now that I think it’s time to encrypt my data. That could be as easy as turning on FileVault, but I’m a bit worried about performance (my current laptop is an iBook G4 1.4GHz/1GB RAM).
TrueCrypt also looks awful good, with good reviews and a well-developed site and documentation.
If there’s no response, I’m gonna try both, one at a time, and I’ll report back here. I don’t usually do the flash drive thing, but I know some people who do, and they’re interested as well.
