I created a quick infographic this weekend to illustrate the trends shown in Gartner's recent Q3 2010 handset shipments report:
The bluer a company is the more its market share is growing, the redder a company is the more its share is being eroded (even if handset shipments themselves are up) - which illustrates nicely the slow decline of the old guard, as a more diverse mix of companies invade the handset space. Fragmentation is here to stay.
