Newly published data from the American Customer Satisfaction Index show that Apple leads other personal computer manufacturers, beating out Dell, HP and others. On a 100 point scale, Apple merited a score of 83, according to the ACSI, a 2.5 percent year-over-year increase and a 7.8 percent increase from 1995, the first year the ACSI measured the PC industry. The annual ACSI is sponsored by the American Society for Quality and University of Michigan’s M. Ross School of Business. It’s derived from phone interviews with customers contacted by using digital-dial telephone samples. More than 70000 consumers are identified and interviewed annually.
