PoE is to power the devices at the other end of the cables, not to power the switch.

  Practically speaking, your devices are almost certainly going to be near a power outlet, too.

    Not in my situation. Just bought a 1950s house with just a single socket in every room. I am fixing that though.

    Not at all. Wireless access points are often high up on the wall or roof. Security cameras too. PoE is a huge advantage.

    As others have said, that's not always the case. I live in a small, 30 m2 (333 sqft) studio and I specifically looked for a PoE access point because otherwise, the AP would have had to be in a closet behind a fridge and an oven. Sure, I could have bought an injector or have set a second cable, but that would've been too much of a hassle.
