Samsung may not be ready to unveil the Galaxy S8 smartphone just yet, but it still has fancy new hardware for us here at MWC. In addition to the Tab S3, the company is showing off two new hybrids that it’s calling the Galaxy Book. They’re ten- and twelve-inch Windows 10 tablets that support new S Pen features, come with keyboards and are light enough to carry around. They’re well-designed and performed quickly during a brief hands-on, and apart from the S Pen support there are a few small features that differentiate the Galaxy Books from rival Windows 10 convertibles.
