Having stated the above, IMO there is no new vulnerability caused by merely using wireless. One can tap into a wire with equal ease, save the headache of relative physical proximity.
In the recent case, there could be no 'hacking' involved at all. The guy must have simply used a network available openly. There are many places where wireless security is not enabled. The owner does not realize that his private network has turned into a 'sarvajanik internet utsav' till he receives his inflated bill.
