Smartphones are big business these days and the market isn't showing any signs of slow down, nor is any predicted in the next little while. New information coming from Nielsen suggests that smartphones are now in nearly 50 percent of U.S. mobile subscriber households with Android claiming 48 percent of individuals who have owned a smartphone. 32.1 percent chose Apple's iPhone and RIM's BlackBerry captured the remaining 11.6 percent. Of those surveyed in February who got their smartphone in the last three months, 48 percent chose Android with 43 percent opting for Apple's iPhone -- not looking good for RIM.
