This is why Best Buy fell; reports of Windows 8 sales not good
Best Buy put in significant amount into training and inventory of windows 8 PCs and Surface tablets:
SEATTLE (Reuters) - Consumer sales of Windows-powered personal computers fell 21 percent overall last month, according to a leading retail research firm, indicating a lackluster debut for Microsoft Corp's Windows 8 operating system, which many in the industry had hoped would revive slack PC sales.
Since the launch of Windows 8 on October 26, Windows laptop sales are down 24 percent, while desktop sales are down 9 percent compared with the same period last year, said NPD Group, which tracks computer sales weekly using data supplied by retailers.
Usually a new Microsoft release boosts PC sales, as many consumers hold off from purchases for several months prior so they can get hold of the latest software immediately.
