A competing vertically-integrated model, in which a single firm controls both the software and hardware elements of a product, has been successful with certain consumer products such as personal computers, mobile phones and digital music players. We also offer vertically-integrated hardware and software products; however, efforts to compete with the vertically integrated model may increase our cost of sales and reduce operating margins.
The only rising company we know does that is Apple. Maybe they're afraid OS X will soon the operating system market or that the iPhone will kill off Windows Mobile?
As a side note, I have to say that the Mojave Experiment is quite convincing.
