The paradox of Android is that Google designed an open-source common operating system that with the intention of commoditising the hardware players and drive prices down.
Instead it gave rise to a single, dominant player.
On paper, Samsung represents fully half the Android market, but if you strip out ultra-low-end Chinese contenders and look at the mid-range market where the bulk of the value lies they represent far, far more. It is outspending Apple on brand in the US and is ploughing record amounts of cash into innovation across the board, from memory chips to flexible LCDs.
Interestingly, Microsoft make more off Android than Google does (because they own key patents).
