iPad users spend three times longer playing games than on the iPhone, and developers also earn more per user from in-app advertising on Apple’s touchscreen tablet, according to a new study from Mobclix (http://www.mobclix.com), a mobile ad exchange network.

As reported by “AppleInsider” (http://www.appleinsider.com), the study shows that games are the largest category of software on the iPad, representing 20% of all options. Within that category, users spend far more time using their iPad than on the iPhone. The study found that iPad users will play the same game three times longer than they would on the iPhone.
