IDC: Apple Mac shows market share gains despite launch of Windows Vista

“Data just released by market research firm IDC indicates that Apple’s share of the worldwide personal computer market rose slightly during the first calendar quarter of the year, despite the simultaneous launch of Microsoft’s first major operating system upgrade in over five years,” Katie Marsal reports for AppleInsider.

Marsal reports, “For the three-month period ending March, the Mac maker registered a 2.6 percent global share, up from 2.5 percent during the December quarter and from 2.1 percent during the year-ago quarter.”

“‘Due to Vista’s January 30 release and the PC sales that resulted from pent-up demand after its lengthy delay, we expected a slight sequential downtick in Mac market share,’ said Gene Munster, an analyst with investment bank PiperJaffray & Co. ‘But strong Mac sales in Apple’s March quarter enabled the company to gain share despite stronger than normal PC sales,'” Marsal reports.

Marsal reports, “The analyst expects year-over-year market share gains to continue for the Cupertino-based company on a quarterly basis, especially as it enters three quarters of significant product releases (iPhone, Leopard, new iPods) and the educational buying season (July).”

  1. That’s impressive. The numbers are small, but to show growth in share of market while your chief competitor has introduced it’s flagship product is not typical. Bodes well for Apple.

  2. That means that Apple could have sold up to 19.23% less computers than they did and still remained with the exact same 2.1% share they had at the same time last year.

    Basically, those 288,000 (or so) “extra” computers are the ones responsible for the marketshare growth.
