This story is from the late 70's, I'm sure that it would be slightly different now.

Three generations of women, a young married woman, her mother, and her grandmother, were asked what kitchen convenience they felt was most important.

The young married woman said that it was her microwave oven.

Her mother said it was the refrigerator with the extra large freezer.

The grandmother was stunned at the foolishness of her daughter and grand daughter. "Well, I don't know what I'd do without running water!"

Generations of tourists have toured without GPS. Probably relatively few people use GPS now. As the units get lighter and cheaper and more efficient (mine burns through batteries pretty quick!) They will be used more, but a GPS is nothing like absolutely crucial.
