When it comes to hardware, Apple's iPhone commands the top spot, but Android is the top dog when it comes to platforms. These are the findings from metrics firm comScore.
Apple's iPhone accounts for 41.8 percent of the OEM market share in the US, well ahead of its nearest rival Samsung, which has 26.1 percent of the market share as of December 2013.
The other players in the listing – Motorola, LG, and HTC – are far behind the leaders, with 6.7 percent, 6.6 percent, and 5.7 percent respectively.
Apple and Samsung have seen their market share since September 2013, by 1.2 percentage points apiece, while HTC saw its market share fall by 1.4 percentage points.
While the iPhone dominates the hardware, Google's Android platform is the leader when it comes to operating systems. According to comScore, it had 51.5 percent of the market in the US by the end of December 2013, while Apple's iOS is closing with 41.8 percent.
Trailing far behind were BlackBerry with 3.4 percent, Microsoft with 3.1 percent, and Symbian with 0.2 percent.
Since September 2013 Android's market share slipped slightly, by 0.3 percentage points, while iOS saw its share grow by 1.2 percentage points.
So, overall no real change since last September, with the big players getting bigger, and the small players increasingly being squeezed out of the market.
