The Fourth Law Of Robotics

My wife has had a robot vacuum on her technology wish list for a long time now. If you're not familiar with the Roomba, they come in several models. These low-flying saucers are a boon to anyone who hates to vacuum. They have sensors that detect objects in their way, as well as one that can sense particularly dirty patches of carpet that may require special attention. Which raises the question: Do robots pay special attention, or is it all merely programming that gives the illusion of specialness?
Whatever the case, my wife had pined for this item long after she received a Kindle for reading digital books and purchased two Tivos that allow us to digitally watch television. These machines allow her to relax more effectively, or at least more digitally, so why not put the digital revolution to work on the household chores? In my mind's eye, I envision scrubbing discs scurrying hither and thither, leaving sparkling trails on every surface they contact. As a family, we step back and admire the way that technology has enhanced our lives.
Until they start to chase the dog. And tear at the drapes. And consort against us in the wee small hours of the morning while they are supposed to be lashed to their charging stations. Soon they have begun to corrupt our digital video recorders, choosing to record hours of home shopping network and infomercials that inspire us to bring even more robot servants into our home. The Kindle has begun to leave faint, subliminal messages behind the text of the Dickens novel my wife had only recently downloaded. That's about the time the drapes catch fire because the little gadgets have begun to move to higher ground and they are testing out their lasers.
Or I could give my wife the gift of doing the vacuuming until I get over my fear of robots.
