People sneer at me for my old-fashioned landline phone. I don't even have a cordless phone; I am completely wired. But consider:

While you're busy trying to kill an intruder or friend by beating him with your cordless phone, or waiting for the radiation you hope your cell gives off to take care of him . . . eventually . . . I will have already eliminated my intruder/friend through simple, silent strangulation by cord. The neighbors will have heard your victim screaming for help -- good luck making your excuses to the police. I, on the other hand, will be able to quietly get rid of the body and go about my business.

Yes, I think we all see who'll be laughing last. I think we'll see.
