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.

By the end of 2013 there will be more iOS and Android devices in use than PCs. Google is using Plus and Android to reposition itself to take advantage of this, extending its reach and capturing far more behavioural data

We believe a helpful way to look at Google is as a vast machine learning project: mobile will feed the machine with far more data, making the barriers to entry in search and adjacent fields even higher

For Google, Apple’s iOS is primarily another place to get reach: we see limited existential conflict between the two. However, mobile use models remain in flux, with apps and mobile social challenging Google’s grip on data collection
