Strategy Analytics predicts that the touch screen user interface in mobile phones will start to see significant growth by the end of 2007, assuming that the right conditions are present. By 2012, 40% of all phones may incorporate touch screen technology. Touch screen interfaces for mobile phones will remain at under 2% of total devices until such a catalytic event occurs, predicted to be at the end of 2007, at which point rapid growth will ignite interest in touch screen phones, growing the market to around 40% by 2012.
