Yes, I think there will be people who are willing to pay a few dollars an hour to use a good computer at an internet cafe. There are still a lot of people who can't afford a good computer or game console to play PC games like Grand Theft Auto 5, Dota 2, League of Legends, etc. There are also many people who can't afford a fast internet connection at home, so they use computers with a fast connection at an internet cafe.
I also think internet cafes are cleaner, and more enjoyable than using a public computers at the public library because fewer people use the computers at an internet cafe, and the computers at an internet cafe are sometimes Gaming PCs because most people these days go to an internet Cafe to play online multiplayer games.
Plus, there are always people who don't like staying home because they don't like their wife, husband, parents, or room mates. Internet Cafe are one place to hang out away from home for people who dislike staying home for different reasons.
