Portable phones (Score 1)

I've seen many houses where a portable phone or a number of portable phones were the only telephones in the house. This is surely a danger to the occupants when the power goes out, right? Isn't this just a product of our reliance on new technology? Can't get cash out of ATMs, can't drive out of an area without entering uncontrolled intersections, perishable food goes bad, can't read slashdot?
