Today, we see an explosion of sophisticated devices and applications in everyone's environment. How many devices don’t you operate every day? In our family several phones circulate (whether or not smart), various remote controls, game consoles, computers, programmable thermostats, GPS devices and so on. Also professionally, I am more than ever confronted with all kinds of applications. Besides the inevitable e-mail and other productivity tools, there are things like ERP systems, simulation software, etc. I have slowly reached my limit.
