If you mean vacuum tubes, then : cost, life expectancy, size. And voltage and temperature, resulting in better portability.

State in the physical sciences usually refers to whether something is a solid, liquid or gas. Water in its solid state is ice, and in its gaseous state is water vapor (not steam!). The liquid state of water is water! Solid state electronics use various semiconductors in their solid states.
Silicon is a solid at room temperature. It has a crystalline structure and is a semiconductor that is widely used in electronics.
Solid state electronics (diodes and transistors primarily)

One can buy a solid state disk at retailers that sell electronics and computer equipment. One can find this item at major retailers such as Best Buy or Staples. One can also find solid state disks online on Amazon.
Anything containing solid state electronics (e.g. integrated circuits, transistors). Practically everything today.

EMP has negligible effect on living things but is easily fatal to solid state electronics. It will perturb but not damage vacuum tube electronics.
A vacuum tube is not a solid-state component. Unlike solid-state devices, which rely on semiconductor materials to control electrical current, vacuum tubes use a vacuum to enable the flow of electrons between electrodes. This technology is largely outdated but was widely used in early electronics, such as radios and amplifiers.

Not without other modifications. The circuits used to turn the solid state relay on will not be suitable for turning a contactor on.
