I believe EFS is available in Windows XP and Windows 2003 Server, too.

Software-based solutions have the advantage that they are somewhat
more testable and reviewable.  If it's all in the disk, you can't
really be sure that the data is encrypted with a static key, and the
passphrase is used for access control only.  The latter approach seems
to be somewhat common with encrypting storage devices, unfortunately.
