And that's why I stress both the written sign-off and actual classroom-type or one-on-one training - to ensure that employers understand what compromises they have to make if they want to use their own devices. Many are not going to be happy about the "right to wipe" provision, either - but assuming nobody is forcing them to use their personally-owned devices for work (and if you are, that's a whole different issue), that's just one of the rules of the game and if you want to play, you have to accept it.
