The reason for the decline in PC shipments is businesses are buying fewer desktop computers as the replacement to the older PCs with Windows XP is already done.
“The reason for the decline of PC shipments in the U.S. was attributed to the desktop market, which experienced a double-digit decline. This was primarily due to the end of the Windows XP replacement cycle,” said Mikako Kitagawa, principal analyst at Gartner.
Meanwhile, IDC in different report said that PC shipments totaled 68.5 million units in the first quarter of 2015, a decline of 6.7 percent, the lowest record since Q1 2009.
“Mobile PCs are being driven by a separate underlying replacement cycle, which led mobile growth in the first quarter of 2015. PC replacements will be driven by thin and light notebooks with tablet functionality. Our early study suggests strong growth of hybrid notebooks, especially in mature markets, in Q1 2015,” said Mikako Kitagawa, principal analyst at Gartner.
The report said Lenovo experienced its strongest growth in EMEA and the U.S. It has become one of the top providers of hybrid notebooks, especially its Yoga line in mature markets.
HP performed moderately well in the first quarter, and it kept its top position in the U.S. and EMEA. HP increased share in the U.S., but in EMEA the share delta from Lenovo, the second-largest vendor in the region, narrowed compared with Q4 2014.
For the first time in six quarters, Dell experienced a worldwide PC shipment decline compared with a year ago. Dell was one of the vendors that benefited from replacement purchases due to the end of Windows XP support in 2014, but sales slowed as the replacement cycle faded.
