Apple's vertical model didn't work for the PC industry for a variety of reasons. But now in the new mobile industry it is so successful, that literally every big company is trying to go all vertical, all the time. Hardware, software, development tools, operating system, mobile and desktop platforms, app stores, single sign-on, cloud services, music, movies, and tv delivery, voice and video communications... Google, Apple, and Microsoft are all trying to build an entire computing stack, back to front, and leave the other guys out. Nokia, Motorola, and HP knew they weren't going to be able to compete in the new vertical world. Samsung is trying to get into the OS game with their Bada and maybe something after that.
