Apple is driving that bus. The company's market share increased by 90.5% and for the first time, the vendor made IDC's top five, coming in at number four. Research in Motion is also doing well in the smartphone space, with a 45.9% increase in market share and the garnering of the number five spot. In the US, Google's Android is making waves with launches of HTC's EVO 4G, Motorola's DROID X and DROID 2, and Samsung's Galaxy S by several carriers.
Volatility seems to loom on the horizon. Samsung, the market's number two vendor, is well positioned. Its Galaxy S smartphone has created a buzz, and its Wave family has been gaining momentum. Conversely, LG Electronics is still searching for a viable smartphone strategy, a hole that new CEO Koo Bon-Joon needs to fill ASAP. Also, SonyEricsson is struggling and fell out of the Top 5 list for the first time since the Tracker was conceived in 2004.
