People need to accomplish tasks. Tools are what help them accomplish those tasks. Often to increase a tool's appeal, tool developers make it multifunctional. The tool suddenly starts to appeal to people who need a knife blade and those who need a screw driver.

Ultimately, the tool gets complicated enough that you need training to use it. You might get the screw driver aspect intuitively, but the part where it acts as an internet access device is opaque to you. Books start to get sold that purport to give you a comprehensive overview of all aspects of the tool.

The problem with this approach is that the focus is on the tool, not the task that needs to get done.
