We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
All extra tools are stored on/in the device itself. It's convenient to have all tools in one place as you don't have to find a place to store them and they are right there when you need them.
