Why do we unplug electrical devices during a lightning storm?

Power Surges: 

>When lightning strikes near a power line, whether it's underground, in a building or running along poles, the electrical energy can boost electrical pressure by millions of volts. This causes an extremely large power surge that will overpower almost any surge protector. In a lightning storm, you should never rely on your surge protector to save your computer. The best protection is to unplug your computer.

Overpowering electronics can cause irreparable damage.
