Microsoft couldn't help mentioning last week that the Windows Store was on the cusp of hitting 100,000 total apps, and now the firm's announced on Twitter that the shop has officially reached the mark. Redmond may not best its competitors in the sheer number of applications available on their respective storefronts, but it did manage to rack up the apps much faster. While it took roughly a year and a half for Apple's App Store to score the same badge, and approximately two trips around the sun for the Android Market, the Windows Store has arrived at the figure in just eight months. With a healthy app shop and Windows 8.1 on the horizon, Ballmer and Co. must be pleased with their eight-month-old OS.
