What’s the point if I can just connect it to my router and not pay any money to anyone, expect some electricity price, which would be like ten times cheaper. My old laptop is capable of a gigabit connection and so my home internet. That’s plenty for anything I can imagine.

Redundancy, I hear you saying! What if you’d have no electricity for an hour? OK then. I’d have another laptop at some else place then, and have two powerful servers for like still one fifth of the price. Can you beat that?
