The global thin and terminal client market deteriorated during the first quarter of 2015, declining 7.8% on year, according to the IDC Worldwide Quarterly Enterprise Client Device Tracker.

Pitted against a strong market in the first half of 2014, which was boosted by a mass refresh of aging PCs, the market in the first quarter of 2015 struggled to keep momentum amidst a lack of drivers and the impact of currency devaluation across regions. Shipments slowed to 1.19 million units, with many projects delayed or scaled back. Outside of Asia Pacific excluding Japan few regions managed to see on-year volume growth.

Looking ahead, IDC expects a stronger second half for 2015 as a number of delayed projects in Asia Pacific excluding Japan should resume, but overall volume for 2015 has been lowered from 5.98 million units in the previous forecast to 5.71 million, with long term growth remaining modestly positive.

"With IT and users alike increasingly more receptive to remote desktop computing, IDC maintains shipment volume should see steady single-digit growth annually through 2019," said Jay Chou, senior research analyst, Worldwide Enterprise Client Device Trackers at IDC. "But, a rising tide will not lift all boats, and we can expect further market share consolidation."
