App downloads on iOS are accelerating quickly enough that they could overtake music in just two months, Asymco estimated on Sunday. The App Store will reach the 10 billion mark in just 31 months, less than half the 67 months it took for 10 billion songs, and at its current rate should overtake iTunes sometime in March. The company's Horace Dediu noted that Apple was now not only recording 30 million app downloads per day but seeing that rate increase.
