I must have missed the posts where people said that it was BS due to a lack of references. Seemed like everyone here was saying "Hell no, my brother and my two friends said they are getting another one, so thats 100%!"
And I entirely agree with you, there should be sources or the article should be disregarded. At the same time people citing their own statistics of how their mom, brother, friends, etc are keeping their devices is also pointless as a single customer, or even 10 customers represents an entirely insignificant percentage of the market share.
Again, I get that there needs to be sources, but don't go around trying to supply your own personal conversion story as that is no more credible. Not to mention any conversion rate an individual and his friends may have represents an insignificant portion in the big picture.
TL;DR: Sources are needed, but quit trying to prove the story wrong by saying "WRONG! My brother and me are both buying android again!", thats equally pointless.
