Just over two years ago, Microsoft unveiled its Surface Book hybrid laptop: a tablet with a detachable hinged keyboard base. It was a compelling concept, with Microsoft pulling off some clever tricks. The base contained a battery, boosting the life of the tablet portion substantially, and could optionally contain a discrete GPU, too. A little under a year ago, the Surface Book was partially refreshed: a new base was offered with a bigger battery and a faster GPU. The tablet portion, however, was left unchanged.
Today, Microsoft unveiled not only a full refresh of the system—both tablet and base are being updated—but a whole new version of the machine. Surface Book 2 (Microsoft is using numerical version number suffixes here, even after abandoning the practice with the Surface Pro) will come in two sizes. There’s a 13-inch model, same as before, but this is now paired with a 15-inch version.
