Customer satisfaction with personal computers is down for a third straight year, according to new data from the American Customer Satisfaction Index (ACSI). The ACSI Household Appliance and Electronics Report 2015 includes desktops, laptops, and tablet computers, as well as household appliances, televisions, and video players.

Customer satisfaction with personal computers fell 1.3 percent to 77 on ACSI’s 100-point scale; desktop computers have the highest score (81) and tablets (-6% to 75) have lost the edge over laptops (-1% to 75).

“Weaker customer satisfaction and slowing sales growth suggest that early enthusiasm for tablets has worn off,” says Claes Fornell, ACSI chairman and founder. “As large-screen smartphones become more popular, they’ve made tablets somewhat redundant—caught in between the mobility of a smartphone and the power and functionality of a desktop.”

Apple continues its ACSI dominance in PCs with a score of 84, well ahead of the rest of the industry. High customer satisfaction across all of its product lines may be attracting new customers to its PCs. Apple’s lead is even larger for tablets.
