Dell and Apple coming off of their massive laptop battery recall are receiving the type of bad press that hurts their customers first.
The Virgin Airlines (think that Branson guy in the hot air balloon) has made the connection that a piping hot battery that catches on fire would actually be a type of flammable material. They are not preventing people from taking this flammable material with them on the plane.
However, they are preventing people from putting it close to the device that enables the flame out, that is the travelers laptop.
Travelers owning Apple and Dell laptops are being required to separate their potentially dangerous batteries from their laptops and keep them wrapped up and separate.
There does not seem to be any work to distinguish whether or not the batteries are actually made by Sony, the company that provided several million batteries in total to Dell and Apple.
