Mats Lindoff, the chief technology officer at Sony Ericsson, a leading handset-maker, points out that the processing power of mobile phones lags behind that of laptop computers by around five years. Furthermore, studies show that people read around ten megabytes (MB) worth of material a day; hear 400MB a day, and see one MB of information every second. In a decade's time a typical phone will have enough storage capacity to be able to video its user's entire life, says Mr Lindoff.
