FYI: I downvoted you because telcodud was explicitly not making a claim that Nexus 7 is "retina," and in your retina-calculation math you completely overlooked the actual (and correct) answer to mycodebreaks' question:
> Nexus 7 [is] not "retina"
> Nexus 7 is closer to iPad 3 than iPad 2.
What you did end up saying is correct but unrelated to the post you were disagreeing with.
