From the article: "Measured in megaflops, gigabytes and other technical benchmarks, the PlayStation 3 is certainly the world's most powerful game console. It falls far short, however, of providing the world's most engaging overall entertainment experience. There is a big difference, and Sony seems to have confused one for the other."
The man does praise multi-player battles in Resistance: Fall of Man, but even Joystiq's own Chris Grant, quoted in the same article, believes the console "doesn't feel finished." Granted, all newly launched systems have hiccups. The real factor is how the manufacturer handles said hiccups moving forward.
