While it is a SMALL hassle, I don't understand how it is jerking
customers around before they've even bought a machine.  As long as the
policy (whatever it turns out to be) is clearly stated on the
wiki/amazon site, by purchasing a laptop they are consenting to this.

With that said, I would probably lean towards preferring unsecured
machines (with pretty boot enabled, of course).
