From the article:
Android and Apple continue to dominate the global mobile market, but Apple is losing (relative) share fast. According to a recent IDC report, these two platforms now have a staggering 90% of global market share, while everyone else is down to 10%.
Both Android and Apple are also still gaining share, while every other platform is losing it. But Android is still gaining share faster than Apple.
In the third quarter, IDC reports, Android sales accounted for a staggering 75% of the smartphone market. Apple sales, meanwhile, accounted for only 15%. Android is still gaining share rapidly, so Apple's share may shrink even further.
All of these gains have come from the collapse of other platforms, namely RIM, Microsoft, and Palm, which, collectively, have collapsed from 49% of the market to 13% of the market.
