Back when we taught Products Liability in law school, one of the topics that always got significant attention and discussion from the bright-eyed students was how to define "defect." The panoply of tests for defective or unreasonably dangerous products never failed to excite discussion, particularly the role of consumer expectations in product assessment.

That same topic is the focus of an interesting recent decision in the Seventh Circuit. See Show v. Ford Motor Co., Nos. 10-2428 and 10-2637 (7th Cir., 9/19/11).
