More than 68.5 million PCs were sold in the first quarter of 2015 (1Q15), a year-on-year decline of 6.7 per cent, and slightly ahead of previous projections.
IDC said that after a strong second half of 2014, thanks to the Windows XP refresh and pockets of price-driven consumer activity, the Q1 market faced multiple headwinds.
There was an inventory build-up of Windows Bing based notebooks, commercial slow down following the XP refresh and constrained demand in many regions due to currency fluctuations and unfavorable economic indicators.
Growth and volume declined with Q1 shipments below 69 million units, the lowest recorded volume since Q1 2009.
IDC's Rajani Singh, Senior Research Analyst, Personal Computing said that despite the decline, PC shipment in the United States declined at a slower rate than all other regions in first quarter, outperforming worldwide trends for the eleventh consecutive quarter.
"The strength from key vendors, adoption of emerging products, improvements in the consumer market and in the broader economy are all positive signals,".
He said that the launch of Windows 10 will consolidate the best of Windows 7 and Windows 8.1. In addition to the free upgrade for consumers for a year after the release, Windows 10 should be a net positive as there is pent-up demand for replacements of older PCs.
Only part of the installed base needs to replace systems to keep the overall growth rate above zero for rest of the year, he said.
"Although shipments did exceed an already cautious forecast, the market unfortunately remains heavily dependent on pricing being a major driver, with entry SKU volume masking a still tenuous demand for higher priced systems that is needed to sustain a more diverse PC ecosystem. Pricing pressure is bringing many premium SKUs into formerly mid-level pricing tiers.
"As more vendors find it increasingly difficult to compete, we can expect additional consolidation in the PC market."
Lenovo held onto the top position with 13.4 million units, and grew 3.4 per cent. The vendor continued to aggressively court expansion outside of Asia, especially closing the gap with competition in EMEA. The company also moved ahead of Apple to capture the third position in the US,

HP remained in the number two position, shipping nearly 13 million PCs with growth surpassing 3 percent, driven primarily by resilient growth in US and EMEA. Although growth slowed from earlier in the year, HP & Lenovo continued to outpace the market and their nearest competitors.
Dell came in at the number 3 position, shipping over 9.2 million units, registering a year-over-year decline of -6.3 per cent, its first negative quarter since 2013Q2. Strong results in the U.S. and EMEA in Q1 2014 contributed to a poor year-over-year comparison.
Acer continued to see good acceptance of its Chrome offerings, Acer shipments slowed in the first quarter - particularly in EMEA where it had seen a strong rebound in mid-2014 but faced pressure from other market leaders in the fourth quarter.
ASUS had a solid quarter with worldwide volume of 4.8 million and growth of 4.4%, supported by growth in Asia. This brought the company just behind Acer - effectively a tie for fourth place.
