AppleInsider reports today on the views of a Barclays analyst who says that the imminent arrival of Microsoft’s Windows 8 OS will not halt the decline in PC sales. In July, according to AppleInsider, Gartners said that there had been a 5.7% decline in PC sales in the US; IDC reported an even heavier decline than that of 10.6%. And, AppleInsider notes, it’s not hard to see the reason for the decline, with massive iPad sales since Apple launched its tablet just two years ago surely having a big impact on PC sales in the consumer, education and enterprise sectors. Both IDC and Gartners count netbooks in their PC figures, and AppleInsider writes that the iPad has virtually destroyed the fledgling netbook market. Elsewhere, Canalys incorporates iPad sales into its PC sales figures, which IDC and Gartners do not, with the result that Canalys finds that global PC sales have in fact grown by 11.7%, but with 19.4% of that belonging to Apple, and the majority of the sales going to the iPad. And AppleInsider notes that it doesn’t look as though the situation is going to get much better for PC makers, even when Windows 8 is released, as Barclays analyst Ben Reitzes says that despite some “short-term ‘excitement’” following on from the release of Windows 8 in September, the PC market will continue to decelerate, with “the rise of smartphones and the iPad…having an adverse impact on the PC market - in addition to macro [economic] factors.” Source: iPad will keep eating away PC market, despite Windows 8 "excitement"
