That's the essence of the "market share" game.
It's a comparison of a bunch of different companies' products... calculated by a 3rd party. A ranking... if you will.
They sit back and rank everything... who comes in first, second, and so on... but do you think Apple really cares about stuff like that?
Apple just sold 37 million iPhones... yet the multi-manufacturer "Android Consortium" sold more. Gee, I wonder why?
But hey... at least Apple didn't post a LOSS this quarter
