Nearly one in three (30%) adults say the cell phone is the invention they most hate but cannot live without, according to the eighth annual Lemelson-MIT Invention Index study. The cell phone narrowly beat the alarm clock (25%) and television (23%) for the distinction in the survey, which gauges Americans? attitudes toward invention. Shaving razors, microwaves, coffee pots, computers and vacuum cleaners were also cited as essential, yet despised, inventions. While the Lemelson-MIT Invention Index found a vast majority of Americans (95%) believe inventions have improved the quality of life in the United States, their strong feelings toward cell phones illustrate both the benefits and unintended consequences of innovation.
