I agree with everything except this last one.  We've always told people
that local devices are disabled by default, because lots of people don't
want to allow users to copy data to removeable drives.  It's a security
thing for them.  Requiring the sysadmin to turn this feature on, if needed
is no big deal in my opinion.

ALthough, I admit that it could be argued that it makes sense in an
educational environment to turn it on by default.
