When you change project every thing not needed is rolled to it
storage position.

Point being with everything on wheels you have a very flexible work
area that can be quite usable in a limited amount of space.

The counter point to that is that, when you start a new project
everything is in the wrong place and you have to move it all
before you can start (which is exactly what I do) :-)

To Meanie's point about the motor sticking out the back of
a contractor style saw - this is the one time you have to
worry about it. With the saw on a mobile base it's easy
to mis-judge how far back the motor is, and bang it into
things while moving the saw.
