“Smartphones accounted for 23.6 percent of overall sales in the first quarter of 2011, an increase of 85 percent year-on-year,” said Roberta Cozza, principal research analyst at Gartner. “This share could have been even higher, but manufacturers announced a number of high-profile devices during the first quarter of 2011 that would not ship until the second quarter of 2011. We believe some consumers delayed their purchases to wait for these models.”
Overall, the earthquake and tsunami in Japan will have a smaller effect on the mobile communication devices market than initially anticipated. There is currently about six to seven weeks worth of inventory of finished products in the channel and about four weeks worth of inventory for components. Gartner estimates that manufacturers' sales into the channel will drop in the second quarter of 2011, while sales through to consumers will be flat."
"Android and Apple's iOS continued to dominate the smartphone operating system (OS) wars (see Table 2). However, the big news in the first quarter of 2011 was Nokia's strategic alliance with Microsoft on Windows Phone 7, and the retirement of Symbian. “This will precipitate a competitors’ rush to capture Symbian's market share in the midtier,” said Ms. Cozza."
