As I understand it, FileVault makes you login before you computer boots to the OS in order to unlock the drive. This means someone getting ahold of your laptop when it is off cannot get at the data.
What are the implications of using FileVault with sleep? I assume the drive is still considered unlocked during sleep. Anyone that opens the sleeping laptop would have to know your login to do anything with the computer, but is the data insecure to someone very determined at that point (assuming they can't guess your password)?
I was considering turning on FileVault but since I never power down, the answer to this will help me decide what value there is in doing so.
