GPD would hit a bullseye with such a laptop form/factor. There is a big community of power-users who are already looking for a small laptop with the might and power of Nvidia/AMD dGPU, e.g., field engineers, scientists, aerospace engineers, software engineers, media engineers, game developers, and anyone who needs a powerful laptop on the go and is tired of carrying a 4-kilo, 18-inch monstrosity with them.
And of course, there is even a much bigger market of gamers that would gladly buy such a device.
