Win App Update reports that Microsoft surpassed 20,000 apps on November 20th. Just before the launch of Windows 8, there were just 3,000 applications, which indicates that developers are showing more interest in Microsoft's new operating system and the opportunity to sell applications via an app store. However, 17,958 Windows 8/RT apps, or 87 percent, of those 20,610 titles were offered as free apps.
Win App Update said that 500 new apps are joining the Windows Store every day, but "only a fraction of these are truly stellar apps" and a true killer app is still missing. Microsoft frequently indicated that it was strongly encouraging some app developers to create versions of their programs specifically for the Windows Store, but the landscape appears to be rather spotty at this time.
In fact, some of the older Windows 8 users may be reminded of the early days of shareware download portals such as download.com and tucows.com, which focused on quantity rather than quality of software. True gems were hard to find and that seems to be no different today.
