Asus, Apple provide most reliable PCs, survey says

Rescuecom received more support calls for Dell and HP PCs, which were the top two PC vendors in the U.S. during the second quarter, according to IDC. Dell rated seventh in Rescuecom's study, with 22.1 percent of the repair calls. Though HP and Dell held close market shares in PC shipments, Rescuecom received 18 percent more support calls on Dell PCs than HP.

Rescuecom established a baseline to rate reliability by balancing the number of support calls with the market share of PC vendors, Milman said. The study was not commissioned by PC makers, and the company has no support ties with PC makers.
