When I hear 'powerful linux laptop' I think essentially portable workstation. This, on the other hand, appears to be very much a gaming laptop (1080p at 240hz with a fancy graphics card).
Good luck to them! Linux gaming has certainly made some strides. I don't think I'd bet my livelihood on selling a ton of these, but it is neat that somebody has decided to try.
On manufacturer's website [0], both the 15" and 17" Stellaris are listed with WQHD IPS-Panel (2560 x 1440 pixels) - I was looking at them just a few days ago.. The article lists 1080p as option, but it's not possible to order.
Which one focuses which way? When I think "workstation", I picture people doing CAD, video editing, and GPU-accelerated simulations and number crunching, in addition to people compiling code.
Games aren't just GPU-bound, either. Unreal says they develop their games on systems with "NVIDIA GeForce GTX 970" and "Six-Core Xeon E5-2643 @ 3.4GHz".
Developing games is different from playing them. The latter takes a pretty beefy GPU (for a given generation) before the CPU is a likely potential bottleneck.
