Samsung Galaxy Book S Windows 10 Ultraportable Laptop Leaks
The Galaxy Book S will run Windows 10 S and is anticipated to be powered by a Qualcomm Snapdragon 855 SoC, similar to the Galaxy Book 2's Snapdragon 850 SoC. We can reasonably expect the Galaxy Book S to also be outfitted with 8GB of RAM.

The images provide us with a great view of the display, keyboard area, and left edge. Samsung has designed it to be suitably minimalistic, using a milled chassis for a premium feel and added robustness.
The display is edged with very narrow bezels up top and on each side, thinner than those found on the Surface Laptop 2. A faint dot above the display confirms proper webcam placement instead of the nosehair shots users get from a camera located beneath the screen. It requires some extra engineering to squeeze a webcam into such a confined space but efforts like this make all the difference in usability.

The left edge drives home the minimalism by offering what appears to be a headset jack and a single Type-C port. There is no indication of whether or not this supports Thunderbolt 3.
All we are left with is this speculation until Samsung formally announces the laptop. We are particularly interested in seeing how ARM-based laptops continue to improve in the coming years. While Microsoft has made great strides towards optimizing Windows for the platform, ARM-based notebooks have not quite reached performance parity with their x86 counterparts. Performance is not everything, however. They already stand as an excellent solution for road warriors who need outstanding battery life and always online connectivity.
