iPad development is accelerating at a fast enough pace that it's already eclipsing Android and BlackBerry, a Flurry study found Thursday. Of all the new app projects started in the past three months, 22 percent were for the Apple tablet. The explosion of interest shrunk the proportion of interest in Android from 18 percent in 2009 to just 10 percent in early 2010, while the BlackBerry's slice of development dropped from four percent to just one.
