To me that is really meaningless unless the iPhone out sold all 6 of them combined. The 6 Android phones are going to split the sells among each other. Putting 2 Android models means each will only get 50% of the sales and at most you might see a 10% increase in total sells.
Now you have 6 phones split roughly the same total number of possible sales.
People keep making that argument that I quoted but really it means nothing because you have to remember sales are divide up among 6 players.
When talking about profits, it makes sense to look at each individual manufacturer. At the end of the day, it's the manufacturers who have to make money. Google will make its money off of Android regardless of how well the manufacturers are doing.
Comparing profitability is not the same as comparing market share. When it comes to market share, the Android manufacturers are "working" together. But when it comes to profitability, everybody is competing against each other.
Also, if Apple has taken 50% of handset industry profits, that means Apple makes as much money as all the other Android manufacturers combined.
