Windows Phone 7's early app market is much more competitive with the iPhone and other platforms than Windows Mobile, Distimo found in its latest study. The average price of any paid WP7 app is now the cheapest of all the stores at about $1.95, or double the $4 for iPhone apps. Microsoft's one-time attempt at pushing premium apps is still evident at the older Windows Marketplace for Mobile, where the average app is three times more expensive at $6.27.
