In the announcement of iPhone OS 3.0 from March, one particular feature stands out as perhaps the most important long-term. And that is the opening up to developers of the ability to access and use external I/O devices via the dock connector and/or Bluetooth.
While many of the other features are certainly welcome and important, including Bluetooth A2DP support, cut-and-paste, universal Spotlight search, and push notifications, none has quite the level of the potential impact on the iPhone OS as a computing platform as the addition of access to external devices. Adding access to external devices brings the iPhone into the world of true multi-purpose computing platforms, like the Mac, the Windows PC, and more.
With this feature enabled, the iPhone can become the core CPU, if you will, of a full computing platform, if so desired. Now one can add such things as external keyboards, external displays, other input and output devices like scanners, bar code readers, and even printers. Heck a full “docking station” akin to those for laptops may even be possible.
Imagine bringing your iPhone home or to work and docking it. This new iPhone dock is connected to a flat-panel LCD on which you can now view the iPhone OS, or at least output from specific applications like the iPod, Mail, Safari, and certain enabled 3rd-party apps including an office application suite. Imagine that your iPhone in the dock is linked to a full keyboard by wire or by Bluetooth and also to a local printer for printer-enabled apps. The possibilities are tremendous.
Through this addition and through further extension of the OS and hardware, the iPhone and the iPhone OS could easily become a complete portable computing platform. Such a platform could indeed change the way we use and think about our “personal” computers in the future. Now perhaps we can see why Apple does not seem to care much for making a netbook. The iPhone as a platform could end up supplanting most of what notebooks and laptop computers do in our lives! And an iPhone or iPod touch with a larger 5″, 7″ or even 10″ screen could easily make a netbook seem far outdated and limiting.
Something to think about….
