Walt Mossberg revealed that Apple dedicates itself to produce a cellphone and a home-media hub in an article of the Wall Street Journal, which is mainly about the different methods adopted by Apple and Microsoft in their products. "In the post-PC era we're in today, where the focus is on things like portable music players, game consoles and cellphones, the end-to-end model is the early winner," states Mossberg. "Tightly linking hardware, software and Web services propelled Apple to a huge success with its iPod player. Microsoft, meanwhile, has struggled to make its component model work on these devices and, in a telling sign, is using the Apple end-to-end model itself in its Xbox game-console business. Now, Apple is working on other projects built on the same end-to-end model as the iPod player: a media-playing cellphone and a home-media hub."
