Apple has now remained atop the American Customer Satisfaction Index of personal computers for 10 years straight. After consistently ranking behind Hewlett-Packard throughout the 1990s and then subsequently failing to outpace Dell, Apple finally scored the highest rating in ACSI’s personal computer category in 2004 and has never dropped below its competition since. Some of the factors that ACSI uses when ranking the companies include the perceived quality and value of the computers, customer loyalty and the number of complaints registered. 9to5Mac points out that although the ACSI’s report is called titled “Personal Computers,” ACSI also includes tablets when deciding a score, which means iPads are included as well as Macs.
