In an age when the devices we own are increasingly becoming multi-purpose, there is still a role for technologies that serve a specific purpose.
Whilst personal and mobile computing devices, home entertainment systems, and even transportation vehicles are becoming increasingly loaded with additional 'features', continuing demand for pure gaming systems, for performance-focused vehicles, and for elite-specification technologies suggest that human nature will continue to be drawn to those technologies that focus on quality of product and/or service applications.
I wish companies would delve deeper into understanding what makes up the core of their business model and then focus their attention on mastering the drivers of it. Yet continually companies try to be a jack of all trades and end up a being a master of none, striving to replicate the success of companies that have managed to pull it off, companies such as Apple. It's time people learnt that these are one-in-a million type companies. Even Apple knows its own limits, hence why there are a number of technology applications even they have stayed well away from!
