Nokia has launched its comeback with two very solid Windows Phone devices at €420 and €270. Next year Nokia, like Apple, will have handsets with uniquely appealing industrial design. However, Nokia will not launch in the USA until 2012 and needs to add cheaper smartphones to the portfolio

Nokia and Microsoft face a hard struggle in establishing a third mobile app ecosystem. However, it is not impossible (Google has managed it in 18 months) and given more devices and the right execution they could manage it

2012 will be the critical year. We believe that the flaws in the Android proposition mean there remains a real window of opportunity. However, if Apple launches a cut-price iPhone then the market will be turned upside-down, again

In this report we outline the current state and likely development of the war between mobile platforms. We discuss installed bases and activity levels, the key issues facing Apple and Android, including Android fragmentation and Google's acquisition of Motorola, and go on to look at the tablet market and the outlook for RIM, Nokia and Windows Phone.

The most dramatic observation from our survey is the surge in mobile data service usage: 48% of UK mobile users now use a data service at least once a month, up from just 30% last year. This increase is substantially all from the increased number of internet-centric smartphones (i.e. iPhone, BlackBerry and Android handsets) in the base

The internet-centric smartphones themselves had substantially no reduction in data usage penetration rates (all at 90%+) despite their volumes surging, with users from all age and socio-economic groups using them for data services. Data service usage penetration on a daily basis actually increased for Android and BlackBerry handsets

This supports our view that it is the nature of these handsets in terms of their ease-of-use for data services that is driving overall usage, and that overall data usage will continue to surge as they continue to diffuse through the subscriber base

In this presentation we show our analysis of revenue growth trends for mobile operators in the top five European markets (UK, Germany, France, Italy and Spain). The historical analysis is based on the published results of the operators, although they include our estimates where their data is inconsistent or not complete.

European mobile revenue growth improved very slightly in Q4 2010, up by 0.1ppt in reported and 0.2ppts in underlying terms, but remained negative

While the improvement is welcome, growth remains very subdued compared to pre-recession levels, especially in Italy and Spain, which continue to lag the growth of the UK, Germany and France

The outlook for mobile revenue growth is bleak, with severe MTR cuts in Germany and the UK likely to drive growth down again over the next six months

Smartphones are rapidly moving to become a majority of UK mobile handset sales, driving a surge in mobile internet use. Even if usage per user (currently growing) flattens out, we forecast mobile internet usage to grow from 1.8bn hours in 2010 to 7bn in 2015: 28% of total online time

This should drive the long promised growth in mobile advertising and we project UK spend, including search and display, will rise to £420 million by 2015, equivalent to 10% of PC internet search/display advertising

We expect the majority of this usage to be incremental to PC-based consumption, as users find new things to do and buy on the mobile web, driving the overall online advertising market to further growth

By 2015 we expect internet-centric smartphone penetration in the UK to reach 75% and mobile internet use to reach 28% of total time spent online. The dynamics and ecosystems of the mobile internet, and in particular the app model, will become a significant part of overall digital strategies

First seen as an interim reaction to slow networks and small screens, mobile apps have become a major new route to market for publishers and ecommerce providers, and are likely to spread to new areas

However, Apple is likely to continue to lose share in the internet-centric smartphone market, and publishers will face a far messier, fragmented world of competing platforms, app stores and payment systems
