The council should have warned me that if I crossed the road without looking both ways, I might get run over – if frivolous product liability lawsuits like this one succeed, innovation will be halted in its tracks, and everything worth having will become prohibitively expensive: Susan Rosenzweig, a former employee of E I du Pont de Nemours & Co says that from September 1993 to September 1994, she was diagnosed as having flexor tendonitis of both lateral wrists, DeQuervain’s syndrome, and repetitive strain injury, and is suing IBM Corp – over its XT keyboard, Hewlett-Packard Co over its mouse and Microsoft Corp over its mouse control software, claiming that her physical injuries were caused by her use of these products and alleging that the three willfully, recklessly, knowingly and negligently failed to warn or advise plaintiff and others of the dangers and hazards of their equipment; she has some pretty ingenious lawyers, because her absurd suit claims that, Motivated by a desire for unwarranted economic gain and profit, defendants… ignored knowledge in existence since at least 1950 of the health hazards of their equipment – even Xerox Corp’s Palo Alto Research Center had not invented or even thought of the concept of the mouse controller in 1950.
