If you're looking for something a bit more exciting on the Surface Pro 6, make sure to check out our senior editor Zac Bowden's video of the Surface Pro 6 running Windows 10X.

Windows 10X won't ship to the Surface Pro 6, but that didn't stop Bowden from managing to get it onto the device and running it through its paces. The video focuses on using Windows 10X as a tablet operating system, so it's worth checking out to see the OS in action on a touch-centric device.
