STILL DOWN: NPD Group says that in the three weeks after Windows 8 launched on Oct. 26, sales of Windows PCs and tablet computers fell 21 percent compared with a year earlier.
WHAT THAT MEANS: There's no sign that Windows 8 made things worse for PC makers. Rather, NPD says the weak sales are a continuation of a trend seen throughout this year.
THE TRENDS: U.S. consumers appear more interested in buying smartphones and tablets than on upgrading their computers. NPD says Windows 8 laptops with touch screens were doing well, helping drive up the average selling price of PCs.
