I can give you a simple example: I live in the capital of my country during the week, and on weekends I always go to my grandparents house. Mobility is a big issue for me, and since I don't have a car, I can't go moving around my laptop on a public bus. That's it. Instead of having to buy another PC for "my other home", I could simply plug one of these and BAM, problem solved.

I guess, but "one of these" will fit in your pocket.

Why exactly can't you take your laptop on a public bus?

Not to be rude, but he may be living in a country where it isn't exactly safe to be carrying around something like that without having it stolen.

Exactly.

Public transportation it's really dangerous.
