During Apple’s Worldwide Developer Conference (WWDC), Piper Jaffray conducted a small survey of iOS developers. They found that 46 percent of iOS developers have also written Android apps, and 36 percent have written BlackBerry apps. Just 13 percent had created Windows Phone 7 apps.
Among the developers who had created Android apps, 100 percent said they preferred Apple’s platform because of better monetization opportunities and the ease of development.
