According to NPD, since the launch date, Windows 8 has captured about 58 percent of Windows computing device unit sales. In the like four-week period after the launch of Windows 7 in 2009, Windows 7 made up 83 percent of Windows computing device sales, according to the firm.
NPD said Windows 8 tablet sales have been "almost non-existent," representing less than 1 percent of all Windows 8 device sales to date.
According to Baker, a less than stellar back-to-school PC sales left a lot of inventory in the channel, which had a real impact on the initial sell-through rates for Windows 8 PCs.
"The strong performance of Windows 8 notebooks with touchscreens—where Windows 8 truly shines—offers some reason for optimism," Baker said. "These products accounted for 6 percent of Windows 8 notebook sales at an average price of $867, helping to re-establish a premium segment to the Windows consumer notebook market."
According to NPD, average selling prices of Windows computing devices have jumped significantly this year, up to $477 from $433 last year. Windows 8 notebooks boast an ASP nearly $80 higher than comparable Windows notebooks last year, while Windows 8 desktop ASPs are up nearly 10 percent, according to NPD.
But while Microsoft and PC OEMs might take some solace from the increased ASPs, the cost of the systems is part of the problem. Those who want a Windows 8 PC may be willing to shell out a little more for it, but for those consumers trying to choose between a Windows 8 PC and a $200 Android tablet, it only makes the decision easier.
