The world of desktop computing is finally going mobile, and the shift can be seen in the explosive growth of wireless data for cellular carriers.
To handle functions from text and instant messaging to mobile MySpace and ESPN, computer users are increasingly turning to the cellphone.
“We are seeing the emergence of a fourth screen,” said Jerry Panagrossi, vice president for operations at Symbian, a developer of advanced cellphone operating systems, citing a historical progression of “movie, television, computer and now the smart-phone screen.”
The newest screen is evolving to adopt more and more characteristics of a personal computer. And many believe that the next big shift will be the convergence of many forms of communication encompassing voice, e-mail, instant messaging and video telephony.
That shift may well be underscored tomorrow when Steven P. Jobs, the chief executive of Apple Computer, is expected to unveil an Apple phone representing his company’s new mobile communications strategy – highlighted by a device that may include Jobsian refinements such as a sleek ceramic case and a transparent touch screen.
