I have one. I offered getting another Gemini as an option. Teenagers though - go figure.
If Planet Computers had the equivalent of a Gemini without keyboard - maybe add a rear camera & LED, and kept the open bootloader and OS options, that might be a win for them. The keyboard is a love it or hate it thing.
But - back to the ROG... It has several relatively unique features that stretch beyond gaming. I have found that gaming centric devices are often better devices for productivity than a lot of the productivity devices. Just as the Note 3 was pretty good at casual gaming for a productivity device.
The ROG's productivity wins: high def screen, gigantic battery, shoulder buttons (next email, previous email maybe?), a real actual landscape docking station. If they were to manage to get dual boot OS to Linux and/or Sailfish OS and an open bootloader into it, that would be a big win. Ignoring the overclocked SoC, heatpipes, rear-facing LED window, snap-on fan, etc...
Looking past the hype, the side-mounted USB C port, shoulder buttons, dual screen clam shell multitasking, dock - all of those have interest to me.
