Fujitsu president Masami Yamamoto has blamed "weak" demand for Microsoft's Windows 8 operating system for its ailing PC sales.
Japan's largest IT services company stressed that it'll miss its annual shipment target for personal computers predominately due to the poor demand for Windows 8.
Yamamoto said PC shipments for the fiscal year ending in March are expected to fall short of an October estimate of 7 million units, which may be around the 6 million market.
Fellow PC manufacturer Acer, meanwhile, expressed similar comments regarding the operating system. Its president, Jim Wong, said that the learning curve for touch will see Windows 8 not being adopted by consumers quickly. He added that the Windows 8 interface itself could "dramatically delay adoption by consumers."
PC vendors' frustration has been echoed in official figures pertaining to Windows 8's commercial performance. While the platform's touch demand is strong, Windows PC sales in the U.S. during the four-week launch of Windows 8 decreased by 21 percent when compared to the same period a year ago.
Companies including Acer, Sony, Toshiba and Dell, among others have all expressed their doubts regarding Windows 8's future. It was recently revealed that the operating system has fallen behind Vista in regards of usage share.
