@pakkuman - share of high end market
I don't think anyone knows for sure, and there would undoubtedly be some argument over the meaning of "high end".
That said it can perhaps be inferred, given that Apple reportedly makes 2/3 of the profit in the smartphone industry, Samsung makes 1/3, and the rest (collectively) essentially break even, then based on this it seems likely that Apple has a a majority share of the high end smartphone market.
If iPhones were way more expensive or cost way less to make that could also account for it, but they cost only slightly less to make (primarily due to smaller displays, which will no longer true with the iPhone 6) and are sold at about the same prices as Samsung's high end phones. One potential difference is that Samsung's phones are quickly discounted to lower prices, while iPhones are very rarely discounted - and when they are the seller eats the discount, not Apple.
The other wrinkle is that Samsung's smartphone marketing costs far exceed that of Apple's marketing costs for iPhone, which reduces Samsung's profitability.
So maybe in the end taking all these factors into account, Apple and Android roughly split the high end market.
