It looks like tablets are moving in on PC sales. Yesterday, Microsoft Windows reported $4.45 billion in third-quarter sales, which was less than the $4.6 billion that analysts were expecting.

Bloomberg has more: “Personal computer shipments unexpectedly fell 3.2 percent in the quarter as consumers held off purchases and shifted to tablet computers, IDC said. Multiyear contracts with corporations and robust demand for Office business software couldn’t make up for consumers who are choosing iPads over a new laptop with Windows.”

Kim Caughey Forrest, an analyst at Fort Pitt Capital Group attributed the loss to iPad sales. She told Bloomberg: “PCs aren’t being bought and if you are going to buy a laptop you’ll look at an iPad. That’s where some of those Windows sales went.”
