As to the first reason, it depends on the second reason. If you wear  
out your machine more by turning it on and off, perhaps more energy  
is used in the need to manufacture, transport, work to save and buy  
and transport another replacement machine.

The second reason, what evidence is there for this? It is not obvious  
to me.

As for the third reason, this is rather a separate issue, leaving a  
machine on is not necessarily leaving it logged on...
