Google’s Chrome OS is really a copy of several products already on the market and an interesting recreation of the thin client concept that Sun and Oracle came up with over a decade ago. You could argue, however, that most successful products, like the iPod and iPhone, are simply better copies of what came before. Really, nobody cares that much — consumers only care about whether a new offering will make their lives better. The Google Chrome OS goes directly to a primary need that mainstream PC users have had unmet since the beginning: an appliance experience.
