Worldwide PC shipments fell by -9.8% in 2013 in the most severe contraction on record, according to the International Data Corporation (IDC). Fourth quarter results were slightly better than IDC expected, but the outlook for emerging markets has deteriorated as competition from other devices and economic pressures mount. In mature regions, the fourth quarter was also slightly ahead of expectations, although the improvement seems driven by short-term factors like a slight rise in XP replacements and is not expected to last long. Overall growth projections for 2014 were lowered by just over 2%, and subsequent years were lowered by less than 1%. However, the changes are enough to keep long-term growth just below zero, and push volumes below 300 million throughout the forecast rather than staying slightly above this level.

Emerging regions were on forecast for the fourth quarter (finishing a dismal year with volume declining by -11.3%), but concerns about the impact of slower economic growth, the culmination of some large projects, and conservative expectations for factors like touch capability, migration off of Windows XP, as well as continued pressure from tablets and smartphones has further depressed expectations going forward.
