Twenty-five percent of PC users admit to slapping, punching, kicking and even hurling their computers, says British manufacturer Nova Tech. The company received more than 4,200 responses to its survey, which explored peoples relationships with their machines. "We were surprised by the number of people who confessed to physically attacking their computers," the company says. Said one survey participant, who slapped his Dell system, "It was so late, and I had so much to doit was like the computer was just taunting me." Theres one Dell customer you can live without.
