I think TrueCrypt is the only good advice there; hiding a folder does nothing for your protection (people don't look at the stolen laptop for your credit card information, regexes do), and using hardware encryption just sounds like a disaster waiting to happen, like consumer-level "hardware" RAID. (RAID controller dies; your data does too.)<p>I'm still surprised that people don't encrypt all their personal information, especially on laptops. Truecrypt doesn't even require a reformat or reinstall -- download it, click a few buttons, and your data is safe and there's almost no speed hit.
