Quite possibly illegal but most definitely rude, a deal for this $55.45 cell phone signal blocker device has been making the rounds of the Internets this weekend.
This metal thingy blocks all cell phone signals around you, to as wide a radius of 40 feet.
But why? DealExtreme has some suggestions:
Perfect for the following senarios:
Class rooms and small seminar halls
Meeting rooms and board rooms
Bus and vehicles (imagine how you can finally have a good undisturbed nap)
VIP and privacy-sensitive scenarios

Yes, but that's just the legal issues. What about setting this off in public and then finding yourself at the bottom of a crowd of pummeling fists, or being cussed at by teenagers whose texting cluster (fill in bad word here) is being disrupted just because you want to prove you're bad?
