Aaron Standard, CEO of analytics firm MarkedUp, talks to Neowin:
We haven’t seen a lot of virtual currency plays on Windows 8 yet, which is a popular in app purchase model on iOS and Android- typically for games. Overwhelmingly what we’ve observed are “feature unlock” in app purchases where a user has to buy access to some premium or advanced feature. Most developers on Windows 8 are still in a “figuring it out” phase when it comes to leveraging the power of the Windows Store – I expect we’ll see some more creative models over the next year. Developers should look into expiring in-app purchases and trial licenses, which are some of the unique features that the Windows Store has to offer.
