Microsoft today defended the $70 monthly plan for the Kin by revealing that the phones would eventually get smartphone-like app support. Mobile communications senior manager Greg Sullivan said the Kin and Windows Phone 7 platforms would eventually merge to where both would run the same apps. He didn't give a timetable but asserted that the Kin was already starting above regular 'feature' phones, particularly through its inclusion of online backup and media sharing through the Kin Studio.
