The Windows Phone Marketplace is growing very fast, just a couple of weeks ago there were around 70,000 apps in their app store, bu now it seems they have reached another milestone of about 80,000 apps which are now available to download. Although the Windows Phone marketplace is not close to Android and Apple iOS app stores which have amassed about 450,000 apps, if Microsoft continues this pace, it could leave the competition in the dust. The prediction as of now by looking at the current momentum is about 100,000 apps by the end of april.
