Laptops with built-in wireless broadband are not expected to become widespread, new research shows.
According to a new report by advisory firm Disruptive Analysis, built-in wireless laptops are only expected to have a global audience of 30 per cent by 2011.
The report forecasts that by 2014 there will be around 150 million users of notebooks with embedded broadband.
However, external mobile broadband USB modems, or dongles, are expected to be used by 58 per cent of global internet users within the next three years.
Report author Dean Bubley said: "Mobile-embedded notebooks are very elegant in concept.
However, he noted that they "suffer from practical and business-model limitations that will restrict their near-term growth, especially during a period of economic uncertainty when buyers will be especially conservative".
The report also forecasts that customer WiMax subscriptions will reach 45 million globally by 2012, with more than one fifth of these being 3G or LTE connections.
