The latest data from Nielsen suggests that between the two of them, Android and Apple's iOS have relegated other smartphone operating systems to sub-single digit market share. The closest competitor -- RIM's Blackberry -- counted only 5% of U.S. smartphone purchases in the past three months. Other operating systems, including Windows Phone, Symbian, HP/Palm's WebOS and others, added up to only 4% share combined.
Overall, Android continues to lead the smartphone market in the U.S., with 48 percent of smartphone owners saying they owned an Android OS device. Nearly a third (32.1%) of smartphone users have an Apple iPhone, and Blackberry owners represented another 11.6 percent of the smartphone market. Among recent acquirers who got their smartphone within the last three months, 48 percent of those surveyed in February said they chose an Android and 43 percent bought an iPhone.
Android's performance is pretty constant, with 48% of existing smartphone owners and 48% of new smartphone purchasers choosing Android phones.
Apple's iPhone has been more popular of late, with the recent release of the iPhone 4S. The iPhone is the device of choice for 32% of current smartphone owners, but has made up 43% of recent smartphone purchases -- entirely at the expense of BlackBerry and the other small-share operating systems.
