A while ago Alan Mendelevich, Founder of AdDuplex, published an interesting article about apps in the Marketplace. Much like a previous Marketplace analysis by Justin Angel we take a look at a sample of available apps, but instead of looking at a Marketplace specific breakdown, Alan walks us through app capabilities.

In the image above (click the enlarge) you can see we have nine app capabilities illustrated by percentage of the 50 top apps taken in the Marketplace (July '11). To give a quick run-through, we have owner identity, location-based services, media library, web browser, phone identity, data connection, microphone, sensors and push notifications. As is to be expected, data connectivity is the most used capability within apps, but it's interesting to see owner identity and phone identity on 24% and 26% respectively.
