The Samsung Galaxy Book is one of the South Korean tech giant's most interesting devices this year, with capabilities far beyond that of a conventional tablet and a form factor that is far more portable and attractive than most laptops in the market. Inasmuch as the Samsung Galaxy Book is a powerhouse device, however, it would have to compete against the current king of hybrid devices, the Microsoft Surface Pro 4.
Note, however, that the comparison between the Surface Pro 4 and the Galaxy Book would involve specs and hardware that are found in the 12-inch variant of Samsung's device. Samsung has also revealed a 10.6-inch version of the Galaxy Book, though its specs are far inferior to its larger sibling's. Thus, for better comparison, the 12-inch variant of the Galaxy Book is compared with the Surface Pro 4.
While the Galaxy Book is powered by a full-fledged Windows 10 operating system, its software does lag a bit when compared with the Surface Pro 4's Windows 10 Pro OS. While the differences between the Pro and the non-Pro version of W10 are fairly marginal, power users would still be able to notice that the Surface Pro 4's operating system is a bit more robust than the Galaxy Book's OS.
