The Nielsen Company on Tuesday released the findings of its latest smartphone survey, which asked respondents planning to purchase new smartphones which platform they intended to patronize. When asked that question between June and September last year, 33% named iOS, 26% said Android and 13% said they planned to purchase a BlackBerry smartphone. When a new group was asked the same question between January and March of 2011, Android slipped past Apple’s iOS platform to become the most wanted smartphone platform according to Nielsen; 31% planned to purchase an Android phone, 30% planned to buy an iPhone and 11% were eyeing BlackBerry devices. Interestingly, indecision also grew between the two surveys — 18% of respondents were undecided when asked between June and September survey while 20% were undecided between January and March.
