Tech finance sleuth Horace Dediu was clearly astute when he determined that it's really Apple and Samsung's smartphone world, and we just live in it. ABI Research just estimated that, combined, the iPhone and Galaxy creators were responsible for more than 90 percent of the profits in the first quarter of 2012 -- mostly through carving out more than 55 percent of the total market share for themselves. We already know that only a handful of companies, like HTC, were making any kind of profit at the same time; ABI, however, has underscored just how much of a mountain Nokia has to climb to reclaim its glory days. For Nokia to completely make up for Symbian's decline, shipments of Lumia phones will have to jump a staggering 5,000 percent this year. The Finnish phone maker is certainly hopeful, but with the 80 percent growth rate in China mostly being led by locals like Huawei and ZTE, that's no mean feat.
