Virgin is banning the use of 'certain' Dell and Apple laptops. Certain? How will they possibly enforce this? Has it occurred to them that the same manufacturer for Dell and Apple also makes the batteries for Sony and others?
What bothers me so much about current security policies is their implementation - cumbersome, half-arsed, and complicated. Everything a good security and safety policy shouldn't be. Dell rightly says this is an overreaction. I'd call it plain stupid.
