The infographics hunch brings forth these days totally rock!! The awesome designs initially attract me but their actual content really keeps me interested. This particular one, comparing smart phones, is really fun.
Thx. We purposely restricted this question to be asked starting in March 2011, to capture the fact that Android apps were well established at that time, and that the iPhone was available on Verizon as well. 15K was a nice sample size, but agree that it will be good to revisit in the future with an even greater number.
