If you have a good WiFi network at home, that's great when your laptop is at home, but if you carry it outside your home you are at the mercy of whatever infrastructure you find there.

Usually if you need to transfer large amounts of data you can still plug in an Ethernet cable in e.g. an office.

Why not? They come up to 300 feet long, in all colors, optionally flat and thin and easily deliver more speed than any (current) WiFi can.

Because usually, you can't just throw a 100m cable through a building and plug it just into some Ethernet socket. And who wants to carry around a spool of cable?

I like how the guy’s wearing a belt of I don’t know what, 7.62x39?, and they point out the stun gun for self defense.

Labeled a cyberpunk but it looks like the perfect 90’s amateur mobile porn production studio.

Yah, well, Mondo2000, California... probably got some inspiration there.
