Appcelerator and IDC (http://www.idc.com) surveyed 2,235 Appcelerator Titanium developers from Jan.10-12, 2011 on perceptions surrounding mobile OS priorities, feature priorities, and mobile development plans in 2011. With 85 new, primarily Android tablets announced at CES, developers are pushing these devices to the top of their priority list.

This quarter’s report shows that Google has nearly caught up to Apple in smart phone popularity and is closing the gap in tablets. Microsoft and RIM made solid gains through their product line update, while Google TV and Apple TV interest dropped off.

As these trends unfold, IDC says it’s becoming clear that the days of mobile app experimentation are over. This year, developers and businesses expect to triple their app development efforts and the average developer is now building for four different devices, says the research group.

Meanwhile, a dramatic increase in the integration of geo-location, social, and cloud-connectivity services underscores new focus on sustaining user engagement, while increased plans to integrate advertising and in-app purchase business models points to a new focus on longer-term financial viability over free brand affinity apps, says IDC.
