An NPD Group look back at most of 2011 has shown the sheer change in the smartphone business in the past year. Android was now the majority, having climbed from 42 percent in all of 2010 to 53 percent from the start of 2011 through October. Despite the pressure, though, Apple too grew share the entire year and actually grew at a faster relative rate, bouncing back from a dip to 21 percent in 2010 to a new high of 29 percent by this October.
