International Herald Tribune in an article titled “War for the 4th screen” talks about a new device from Apple. It is rumoured that the new device will be a true pocket computer capable of handling music, video, productivity tasks and mobile communication.

For functions from e-mail and instant messaging to mobile MySpace and ESPN, computer users are increasingly turning to the “fourth screen” - the one on their cellphones - which is evolving to adopt more characteristics of the three previous generations of screens: movie, television and computer.

That shift may well be underscored on Tuesday when Steven 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 Jobs-inspired refinements like a sleek ceramic case and a transparent touch screen.

Only time will tell whether this will turn out to be the pocketpc killer like what iPod did to other MP3 players. Well, one thing is sure, it won’t be that easy.
