That stunning growth gives hope to users of Windows Phone 7 models. The Windows Marketplace celebrated a milestone of its own and now has 5,000 apps available. Unlike the apps available for Android a small minority of 28% are free for the Windows Marketplace and 22% are games. AndroLib's breakdown shows that the free downloads in the Android Market control 63.3% of the pie, and only 14.8% are games.
So what is in store for these two markets for the next 12 months? With the better game playing capabilities of future Android handsets, more games should make their way into the Market. Many Android apps are supported by ads, which explains the large percentage of free apps. But as other payment options become the norm for the store, the future could see more paid apps for Android. As for Windows, the amazing parabolic growth of the Android Market will be a goal to aim for, but it will all come down to handset sales and whether or not phones using Microsoft's new mobile OS can ring up sales at the same rate as those handsets using Google's open source OS.
