Analyst firm IDC has published a report claiming that 916m smart connected devices shipped last year. That’s a category that includes PCs, smartphones and media tablets, and one that IDC thinks will generate 1.1bn shipments in 2012, rising to 1.84bn by 2016. There’s some good detail in the future forecasts too. IDC thinks that between 2011 and 2016, the percentage of these devices that are PCs running the Windows OS will fall from 35.9% to 25.1%. That means they’ll be overtaken (if IDC’s prediction is right, obviously) by devices running Android, which it expects to grow from a 29.4% share to 31.1% share by 2016. Apple iOS devices are predicted to grow from 14.6% to 17.3% in the same time period. IDC adds that Asia/Pacific countries, especially China, will be the key drivers of smartphone growth.
