What G.P.S. Can Do for Your Marriage

Many improvements in technology shift the production possibility frontier outward. Many of these increase human happiness, and a few do this by increasing marital harmony (Viagra?).
One piece of technology my wife and I just acquired does all of these while saving that most precious of all things — time.
Our car’s G.P.S. device — Gertrude, as we call ours — led us from a rural road in Portugal back to our condominium with no hassle, no spousal arguments about which road to take, and no wasted time driving around trying to find the correct route.
I wonder how many other devices do as much to improve married life?
