GPD Win Max 2. I love this little thing so much. ~8-10 hours of battery life, up to 64GB RAM, 16-core Ryzen on the newest model, 2K display. It's only 10 inches and it can run Cyberpunk with raytracing. It also has two slots for SSD's and an optional LTE module.
The sticks are hall effect sensors, so there's no drift (looking at you, Nintendo). The keyboard is backlit and feels way too satisfying for something this small. (I actually like typing on it)
On the backside of the device, you can slide out two metal covers and place them on top of the thumbsticks, hiding them and making the device look more professional.
I once took this to a customer doing a training session and dropped the line "This thing is more powerful than all the computers in this room" and it was probably true.
