n 2008, there were almost 162 million Smartphones sold, surpassing notebook sales for the first time. Just over 49% of Smartphones sold in 2008 were based on Symbian OS, a significant drop from a near 65% share it enjoyed one year earlier. While this is in large part due to the relatively poor performance of Nokias Smartphone range, it is also an indication of the popularity enjoyed by competing platforms including Linux, BlackBerry OS, Microsoft Windows Mobile, OS X iPhone and new entrant Android.
