Windows Mobile is losing out to Android in the US, new figures suggest, as more and more smartphone users jump ship from Microsoft to opt for Google's platform.
Windows Mobile lost 20 per cent of its user base in the first quarter of 2010, according to the latest figures from ComScore.
Almost 70 per cent of the US market is still shared between Apple and Research in Motion (RIM) with the iPhone and BlackBerry platforms respectively.
Although Apple managed to retain its position in second place with a 25 per cent share, RIM is the clear market leader, with 43 per cent of Americans choosing its smartphones over its rivals.
Android now has over seven per cent of the US market, but has managed to double its share in three months.
This means that it is quickly catching up with Windows Mobile, which now has just under 16 per cent of the market.
Microsoft has not made the position of its current generation smartphone platform any better by announcing that its current range of apps for Windows Mobile 6.5 will not be compatible with Windows Phone 7 Series phones when they are released late in 2010 or possibly in 2011.
The mobile market in America is now closing in on a smartphone majority, with the statistics showing that 43 per cent of consumers have smartphone-class mobiles.
Social networking is a major catalyst in the growth of smartphone popularity in the US and almost a fifth of smartphone users are checking up on their profiles and updating their status using their mobiles.
