Microsoft dominated PCs and Nokia mobile phones, but both are irrelevant in the dominant model for tech in the next decade, smartphones and tablets. An acquisition may have been necessary, but by itself it solves nothing.

Smartphones are now half of all mobile phone sales, and the 255m smartphones and tablets sold in Q2 2013 dwarf the 76m PCs sold. Microsoft now powers less than a quarter of all the personal computing devices being sold.

Microsoft retains a leading position in enterprise and in console gaming. But if it cannot return to relevance in consumer, the strength of the whole business will suffer.

Amazon, Nokia and Apple are expected to announce new mobile devices in the next fortnight. We outline the main products and features expected and their implications

Around 125m smartphones were sold globally in Q2, up over 30% from Q2 2011. Around 450m mobile handsets were sold in the quarter, giving smartphones a volume share of around 28% Apple and Android dominate with a combined of 85% of units sold, and a cumulative total of 810m devices running their mobile platforms. Of these we estimate that 680m are active, of which 95m are tablets Android arrived later and has grown faster, but Apple’s market share of smartphones as been steady at 20-25% for several years: Android’s growth has come at the expense of Nokia, RIM and feature phones

In this report we show the findings of our 2012 UK mobile user survey. The report is a wide ranging analysis of the mobile market based on our consumer research, focusing on the competitive landscape among the mobile operators and smartphone manufacturers, and the changing consumer behaviour that has and will continue to impact the market

Mobile operators, services and handset makers are diverging – they all come to the MWC but have increasingly little to say to each other as their businesses move in very different directions

In the context of -5% European mobile revenue growth, the MNOs at the MWC were a sober bunch, focusing on industrial services, defensive moves around messaging, and a (not unreasonable) plea to regulators for some relief

As competition in Android intensifies between hundreds of black plastic rectangles, the picture for OEMs looks tough but Google’s failure to make Android work well for developers may also start to bite, leaving an opening for Nokia and Windows Phone
