I thought the link between pinball and video game cabinets was dubious, especially considering the article acknowledges a few times that there was a multitude of coin operated games out there before Computer Space was released in '71. Not that there wasn't a connection in the cultures of the two games, but they're obviously two distinct platforms. Maybe an argument can be made for the contrary, however.
I think the article points to an interesting dichotomy in the existence between public versus private gaming spheres. There's not a good reason I can think of for arcades not succeeding as a semi-permanent business model. Public consumption of other media works just fine: e.g. movie theaters, art galleries, concerts. That's all theoretically of course; the article quotes a number of people as claiming that the "economics aren't there anymore." It comes off a little too close to insinuating that the decline of public video gaming was some sort of economic/historical inevitability for my liking: this sort of determinism is bad writing and leaves a lot of questions about the actual factors which led to the arcade's decline.
(Maybe Ezio can come in and write something about the culture wars that emerged around both the pinball and the video game arcade. There's an obvious comparison to the 1954 Comics Code and all that jazz that I'm sure he knows very slightly better than me.)
In any case, the article is definitely worth a skim for those with an interest in gaming history.
