Piper Jaffray, an investment banking firm that earned $7.4 million in net income last quarter, is betting on Android in a big way. Today, Piper Jaffray predicted that Android's market share will pass the 50 percent mark in the next five years. Don't look for the rise to the halfway mark to happen all at once. The report explained, "We estimate Google will control 14.9% of the smartphone market through Android in 2010, growing to 23.2% in 2012."
