... In the summer, leaving the PC on wastes energy twice. First to run the PC and second to run the air conditioner.

Using this logic, you would get the wasted energy back during the winter since it would help heat your room. Unless you have your computer in a closet (Does anyone cool/heat a closet?), the heat output from your computer will have a negligible impact on your heating/cooling bill.

Turning desktop computers off reduces the chance of damage from power, spikes, black outs and brownouts. In 30 years of home computing, One hard drive died after a power flicker.
Laptops have the external power converter, which reduces the chances of power fluctuations damaging equipment.

We had a Dell with Windows Vista that got hit by thunder or lightning, and it damaged the NIC card. I had to buy an USB adapter to plug into it, so that we could get internet on it. After the computer broke down and we bought a new one, I don't know what happened to that adapter.
