It was cool in 2010 when I was like 14 and had an iPod touch but didn't have wireless Internet access at home because my parents didn't understand the concept of a router and thought they would have to pay for it, plus christian concern over porn and corruption on the net. So I could go to like McDonalds or whatever, download all of these game review articles, web novels, and whatever else I was into at the time so that when I got back home I could still interact with the web.
Nowadays, yeah I don't really get the point. Everyone's permanently plugged in so a regular bookmark is fine. Also in case anyone was concerned, my buddy eventually gave me his old router and I secretly set up WiFi in my house so I was good for the rest of the time I lived at home 👍
