Worldwide PC shipments totaled 90.3 million units in the fourth quarter of 2012, a 4.9 percent decline from the fourth quarter of 2011, according to preliminary results by Gartner, Inc. Analysts said the PC industry’s problems point to something beyond a weak economy. “Tablets have dramatically changed the device landscape for PCs, not so much by ‘cannibalizing’ PC sales, but by causing PC users to shift consumption to tablets rather than replacing older PCs,” said Mikako Kitagawa, principal analyst at Gartner. “Whereas as once we imagined a world in which individual users would have both a PC and a tablet as personal devices, we increasingly suspect that most individuals will shift consumption activity to a personal tablet, and perform creative and administrative tasks on a shared PC. There will be some individuals who retain both, but we believe they will be exception and not the norm. Therefore, we hypothesize that buyers will not replace secondary PCs in the household, instead allowing them to age out and shifting consumption to a tablet.” “This transformation was triggered by the availability of compelling low-cost tablets in 2012, and will continue until the installed base of PCs declines to accommodate tablets as the primary consumption device,” Ms. Kitagawa said. “On the positive side for vendors, the disenfranchised PCs are those with lighter configurations, which mean that we should see an increase in PC average selling prices (ASPs) as users replace machines used for richer applications, rather than for consumption.” During the holiday season, consumers no longer viewed PCs as the number one gift item. Given a burgeoning variety of increasingly more attractive devices and services, consumers directed their attention elsewhere. Analysts said there was uptake of very low priced notebooks as a part of mega holiday deals, but this uptake did little to boost holiday PC sales.
