High school student Alex Guyot says his anecdotal evidence backs up Piper Jaffray’s study of American teens:

Android isn’t in any danger of extinction in this high school’s population, but the dominance of the iPhone is blatantly obvious. Apple would have to have a massive blunder to change the direction the iPhone’s popularity with teens is heading. In the mean time, Piper Jaffray’s study stands true.

I should clarify that my point in this post was not so much to cast doubt on the study or declare Piper Jaffray “in the tank” for Apple. It was that we need to be careful to treat these situations — situations where the firm that comes out on top in the study is a client of the firm conducting it — the same whether it’s Apple or Samsung.
