Re: A real market?
I was wondering the same at first. But as the Boeing Black is intended for government agencies mainly, and companies engaged with those agencies, for defense and security I suppose there is a market and Boeing saw the opportunity.
The self-destruct feature, however, would be useful for other people, too. Maybe after this Apple, Samsung, or any other manufacturer add a self-destruct capability to their devices as well.
About Angry Birds, worry no more. Rovio will make sure every government agent will have their quota of secure Angry Birds play. :D
