But Asus’ computers are gaining fast on Macs in Rescuecom’s fourth annual report
Rescuecom measures reliability by dividing each manufacturer’s U.S. market share, as measured by IDC, by the percentage of calls requesting Rescuecom’s service on each maker’s machines.
Although Apple had the highest score in Rescuecom’s 2010 report, its lead over its nearest competitor shrank from more than 200 points in 2008 to just 60 points this year.
In its 2006 report, Rescuecom indicated that its survey was based on 20,000 calls to its 800 number. No comparable figure was provided in this year’s report.
And as several readers have pointed out, Rescuecom’s numbers don’t include machines repaired either by corporate IT departments or through manufacturer-supplied service contracts, such as AppleCare.
