I am not exaggerating when I say that this is the best laptop that I have ever owned. The form factor is perfect, it's small enough to be ultra-portable but not too small as to not be able to work comfortably with it. I had a GPD Pocket 2 before this and while I enjoyed the portability of it, I always felt that it was a tad too small.
The build quality of the Win Max 2 is exceptional. You can really see and feel the quality, with the all metal construction. The keyboard is great to type on and the trackpad is quite good for it's size (supports multi-touch gestures).
The built in game controls are amazing. The only things I would personally like to see changed with them for the next generation is that I would prefer the left thumbstick to be on the right of the directional pad instead of the left. It's awkward to work the left triggers with the position that it's in.
The mouse control mode for the game controls is also not as flexible as it should be in the sense that the triggers can't be remapped at all, and the a, b, x, y buttons can't be mapped to click or scroll (which would be great). It should also be possible to set the cursor sensitivity and acceleration.
I personally don't use the built in mouse mode at all, I instead use the Handheld Companion software which is amazing. I have it so when I long press the start button it switches between game control and desktop control modes in the software. I have the x, b buttons mapped as left and right click, and the a, y buttons mapped as scroll down, scroll up.
I find this extremely comfortable to use and I have been using the joystick to control the mouse almost all the time as I find it more comfortable to use than the trackpad. It reminds me of using the mouse control knub on my old IBM Thinkpad, only it's more comfortable and precise. It's really cool to be able to use a combination of the joystick, the trackpad, and the touchscreen to control the mouse. Sometimes I switch it up a bit to help with fatigue.
I have the model with the AMD 8840U CPU, 64GB of RAM, 2TB OS drive, I have added a 2TB M.2 SSD in the expansion port and a 1.5TB SD card in the Micro-SD slot. This thing is powerful enough to play even recent games at reasonable settings. It's also nice to be able to control the TDP via Handheld Companion to reduce battery drain. I have it use the full 28W TDP when plugged in but it scales down to 15W TDP automaatically when on battery. The CPU has 8 cores, 16 threads, boosting to as high as 5ghz.
If you're looking for an ultra compact powerhouse this is it. I highly highly recommend it.
