PC World reports that anticipation of Windows 8 devices coming out this fall has predictably led to sluggish sales of PCs in the past quarter as customers wait to decide whether they want in on the new operating system, according to an IDC report.

Until they get more information -- and that could mean actually seeing Windows 8 devices -- a significant number of these potential buyers will put off buying, says IDC analyst Jay Chou. "The announcement of a Windows 8 launch date, as well as broader communication of new features in the OS, are key steps that would help to address uncertainty about new product availability and help consumers and channels plan their purchases," he says.
