Laptops work pretty well in that regard. Sure, I saw a few with broken hinges over the years, but saying that hinges don’t work is overblown IMO.

(And I say this as an owner of a 1st gen DS with broken hinge. That was probably a design error.)

You did what?

My ISP offers static IPs only on business plans that cost quite a lot more than the consumer rates. Difference is probably ~20€ per month. Plus I need the hardware and energy cost.

My VPS costs 10€ per month.

The “port forwading” thing is probably the biggest challenge. There is no “single tutorial” on how to do port forwarding. Some routers don’t even have a setting for it. And most people probably don’t have a public static IP, and I’ve seen provider fees that are so high that it’s cheaper to get a VPS instead.

And additionally, even if you manage the port forwarding, it is still some additional risk to host a public service on your own personal LAN.
