<p>In the 1980s, power toolsets consisted of five or six power tools but were delivered with a single motor attachable to each of the tools. The tools themselves were motorless.

This approach has a long tradition and was also common, for example, with early electric kitchen appliances. Such systems have become uncommon. However, looking at current consumer electronics it seems that a similar trend might be emerging. This time the expensive and complex components are the user interface and the embedded processor. Hence, this component is shared among appliances.</p>
