Apple helped advance the idea of a company being successful by being both a software and hardware manufacturer. Google is advancing its Android software with its Nexus 7 tablet, and Microsoft is doing the same with new Windows software and the Surface. Microsoft is also betting on the success of its phones via its partnership with Nokia (NOK)
Nokia has taken a beating over the years in the phone market but not without reason. Nokia is dependent on the operating systems of other software companies (Microsoft) and has had little innovation when compared to Apple. Nokia has seen little net income margin improvements and has debt on the balance sheet; Apple is debt-free with continuous innovation and improving net income margins. Apple also better manages its SG&A costs than Nokia, which leads to improving margins.
