Why U.S. Android Handset Sales Are Outpacing the iPhone

Kevin C. Tofel of Gigaom writes: "More handsets sold in the U.S. during the first quarter of 2010 were running atop Google’s Android than Apple’s iPhone operating system, according to the latest findings of The NPD Group. Android smartphones accounted for 28 percent of sales; the iPhone, just 21 percent (both still lagged behind Research In Motion’s BlackBerry platform, which was the market leader at 36 percent). So what’s propelling Android past the iPhone?"
