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

Apple’s iTunes will add free-to-the-user online and mobile radio to the platform in the autumn of 2013, meshing music purchase with enhanced tools for discovery.

iTunes Radio also meshes with Match, the cloud-based music storage and retrieval utility sold for $24.99/year, whose users will enjoy ad-free online and mobile radio.

The main casualty of iTunes Radio is likely to be #1 US internet station Pandora, which this week launched the next phase of its battle to win the better royalty terms of commercial radio.

Apple’s numbers have got so good they’re bad: after growing at over 50% for two years, relative revenue growth has, inevitably, slowed. The products remain very strong, and direct competitors continue to have little impact. (Apple’s mobile phone market share has never been higher, for example.) However, the premium phone market itself, which the iPhone dominates, is at a potential tipping point.

Last week Samsung updated its flagship Galaxy S smartphone with a solid incremental upgrade that will cement its dominance of the high-end of Android, helped by a $14.7bn marketing budget and wide distribution

Impact will be strongest on other Android OEMs: the preceding S3 was heavily outsold by the iPhone and the new model is unlikely to change this, with similar design and positioning

Samsung’s launch event found room for a tap-dancing child and a live orchestra, but Google and Android were invisible. Samsung is clearly trying to relegate Android to a commodity and make its own brand dominant

Major European mobile operators were downbeat, with mobile revenue growth in Europe still massively underperforming the US, and their (misplaced in our view) anger at the OTT players being channelled into promoting new mobile OSs to compete with both Apple and Android

Samsung is cementing its dominance, while the other branded players focus on flagship models to try to cut through the noise. Meanwhile the flood of Android from Chinese OEM/ODMs is growing, at increasingly good quality. All other mobile platforms appear increasingly marginal

Superficially the handset industry appears to be stabilising around Apple, Android, and Samsung, plus the Chinese long tail. However, Apple, Google/Moto and perhaps Amazon may well all have disruptive moves planned for this year
