Market Penetration
Market penetration is a measure of how many of the total mobile phones being used by subscribers are smartphones. Globally, the average is around 14-16% (Q4 2009), but can vary depending on definitions used. This figure has grown significantly over the last few years and is expected to continue to do so as more smartphones are sold in the mid and low end of the market.

Of the five biggest EU countries, Italy has the highest smartphone penetration rate at 32%, followed by Spain on 28.3% and the UK on 22.9%, Germany and France have lower rates at 16.5% and 15.2% respectively. The US has overall smartphone penetration of 18.2% (42.7 million smartphones from 234 million subscribers).
This means that roughly one in every three mobile phones sold in Italy is a smartphone. There are approximately the same number of smartphone subscribers in Italy as France and Germany combined (despite the fact they have more than double the population). There are 15 million smartphone subscribers in Italy, 11.1 million in the UK, 9.9 million in Spain, 8.4 million in Germany and 7.1 million in France. Collectively the EU 5 has 51.6 million smartphones.
comScore also sub-divide smartphone
subscribers into high-end (£35+ or €50+ per month contracts) and mid and
low end. Unsurprisingly comScore have found that mid and low end
smartphone subscribers are growing significantly faster than high-end
subscribers in all markets (UK: 76% versus 60%, Germany 41% versus 18%).
Similarly, the countries with high smartphone market penetration
typically have a higher proportion of mid and low tier smartphones
versus high end smartphones (Italy: 78% / 22%, UK: 62% / 35%, France:
67% / 33%).
Smartphones by platform in Europe
The data below is a 3 month average (ending January 2010) showing the share (%) of smartphone subscribers by platform in the UK, France, Italy, Spain, the EU 5 (an average of the previous European countries). The US data from an earlier comScore press release is also shown.

Symbian is the leading platform in the UK (46%) and France (40%). In the UK, the major competition comes from RIM (18.7%) and Apple (20.5%), in France it is Apple (29.9%) and Microsoft (20%). The UK has one of the more competitive markets for smartphones and is a relatively level playing field in terms of consumer choice. All the major platforms' high end devices are available on similar terms (devices for free on £35+ per month 18 month contracts) and marketing campaigns across the board.

In Italy and Spain, Symbian dominates the market with around 75% share. The data shows a strong contrast from the UK and France. It is illustrative of the differences within an area, Europe, that is sometimes considered homogeneous when reporting statistics.
Country culture (preferences) and degree of market entry for the respective platforms will play the primary role in accounting for differences. Due to higher overall market penetration, as discussed above, both countries have a higher proportion of mid and low tier smartphones as a total of the smartphone market, compared to other countries (78% in Italy, 62% in the UK); given Nokia's strength in the mid and low tier (5800, 5530, E63, etc.), the majority of such phones are likely to be Symbian-powered, which, perhaps, gives Symbian added strength in these markets.

Germany's platform figures are somewhat similar to France's. It shares both a similar market penetration (relatively low) and a higher than average share (19%) for Microsoft (Windows Mobile) devices, but the iPhone has a small share (15.3%), with Symbian taking up the slack (55%). Germany (and to a less degree France and the UK) have a legacy of operator success in pushing own brand (and more recently HTC-branded) Windows Mobile devices.
Looking at the EU 5 as a whole, it is clear that Symbian is, by some margin, the most dominant smartphone platform (60.9%); double the size of its two nearest rivals combined. Apple's iPhone just edges into second place (14.5%), from Microsoft's Windows Mobile (14.1%), with RIM in fourth place (8.3% - a strong contrast to its market position in the US) and Android in fifth place (2%).

The data for the US shows the gulf between Europe and the US. RIM is the market leader with 43%, iPhone is second with 25.1%, Microsoft is in third with 15.7%, Android is fourth with 7.1%, Palm is fifth with 5.7% and Symbian doesn't register in comScore's numbers (in reality they are just a few %). RIM is the best selling platform in the US, but its dominance can also, partly, be explained by maturity in the market (compared to iPhone and Android) and longer device retention periods than for other platforms.
The US is an unusual market: with a few
exceptions, the rest of the world generally follows the European pattern
(or more extreme versions). If anything, like Japan and South Korea,
the US is a market apart; something of an odd man out. It is worth
remembering this when you see reporting that draws global inferences
based on US data.
Usage statistics
The data below is for all mobile phone subscribers (i.e. not specific to smartphones), but once again illustrates regional variations in what people are using their phones for.

Developers take note
These statistics shed some interesting light on the European smartphone market, especially for developers. Symbian continues to provide the biggest market opportunity in Europe by some margin. Any service or application provider wanting to target a significant portion of smartphone users in Europe must provide a Symbian application.
However, it should be noted that numbers alone are not enough. Distribution systems and a consumer willingness to buy are also important; this is why initiatives such as the Ovi Store and PlayNow Arena are so important. With that said, the mobile usage statistics in Italy do show the highest application usage in Europe (37%), which given Symbian's dominance there, suggests the widely held belief that Symbian users do not use applications may not be true.
Regional variations within Europe are well worth considering when
allocating resources for future developments. For example, it might be
worthwhile localising content into Italian since, numerically, it is the
biggest smartphone market in Europe.
Statistics
Clearly figures do vary, for example Nielsen released a report yesterday showing that US smartphone penetration was 21% in Q4 2009. There are some issues around how you define a smartphone, which can lead to different numbers. As ever, the context of what is being measured and the method is very important in assessing accuracy and drawing any meaningful conclusions.
