Only if there's requirements from above... or if you're going to be
pulling drives as backups, say, and taking them out of there.

It would be a good idea.

Depends on who has access, and how much your data's worth.

The US gov't, and federal contractors, require encryption on all laptops.
Many companies are starting to go that way. Do *you* really want to read

and tell you what happened to all the information on your laptop? Or how
someone broke into it, and used it to get to *their* network?
