Scale and polarisation in mobile

There are lots of ways to look at the global handset industry, but the polarisation evident in this chart is pretty compelling. Not shown - the hundreds of 'other' manufacturers, mostly in China.

The CFO of Qualcomm recently described the industry as a barbell - Apple and Samsung at one end, then the smaller and mostly sub-scale players (though some, such as Sony, are showing signs of increased health, albeit from a low base), and then at the other end, invisible, the Chinese. 

As an aside, this also illustrates the way that Apple has become so cyclical that it's really only the December quarter that gives a good directional steer.
