This year, Microsoft and Apple are both introducing new versions of their operating systems with important changes to their user interfaces, and with a flurry of publicity. A third major company is also overhauling its PC operating system, but you probably won’t hear much about it.
Google redesigned its PC operating system, Chrome OS. While Google is a major rival to Apple and Microsoft in things like search, smartphones and browsers, Chrome OS hasn’t dented the competition in the year since it emerged. It was meant to be radically different than Windows and the Macintosh operating system, a refreshing change for a new era. But it had serious limitations, principally that it ran only apps inside a browser on a handful of special, low-powered laptops called Chromebooks and could do almost nothing when it wasn’t online.
