Smartphones are getting kind of popular nowadays, in case you hadn’t noticed. The latest figures from IDC show a 79.7 percent expansion of the global smartphone market between this time last year and today, which has resulted in 99.6 million such devices being shipped in Q1 of 2011. That growth has mostly been driven by Samsung, which has more than quadrupled its output to 10.8 million shipments in the quarter, and HTC, whose growth has been almost as impressive. The other big gainer is Apple, with 10 million more iPhones shipped, but the truth is that all the top five vendors are showing double-digit growth. In spite of Nokia losing a big chunk of market share and RIM being demoted from second to third in the ranking, both of those old guard manufacturers improved on their quarterly totals. IDC puts this strength in demand down to the relatively unsaturated smartphone marketplace, and believes there’s “ample room for several suppliers to comfortably co-exist,” before ominously adding, “at least for the short term.” And after the short term, our break-dancing robot overlords take over.
