My question to you: How did you afford a GPD Win?!
Saved up for it. Just wish I hate waited for the later Releases where they fixed a few things in it. Increased Cooling, few BIOS and Software improvements. There are many Pros, but a lot of Cons as well.
Pros:
Windows Device WITH Integrated GamePad and Keyboard. With the ability to change between different Controller Types (DInput for older Games and XInput for newer Games)
Device has a full Sized USB Port so you can have a USB Storage Device AND use a MicroSD Card
Bluetooth
Nice Compact size
Joysticks and DPad can be replaced if they ever start going out on you
Cons:
64GB Storage
Device could have been a little thicker to put the Shoulder Buttons in a better spot. As it stands now, you go to press L/R2, you might also hit L/R1 at the same time
L/R3 are separate from the Joysticks. So if you are running a FPS Game, you got to work some magic trying to Move, Aim, AND be Crouching at the same time.
Device could have been a little bigger/wider to put in a Full Keyboard with NumPad.
Mouse Nub like the N3DS would have been a good idea. That way the Gamepad Switch could be locked on either Input Modes. Wont work for certain Emulators/Games if you move the Switch after the Game is running, and also might be lost if you switch to Mouse Mode, then back to Controller Mode. Would be better with a Mouse Nub with 2 small Buttons for Left/Right Click.
Wish the Device could work with a SPen like the Galaxy Note Devices for increased Accuracy.
Need to be able to have a way to Upgrade/Increase CPU, RAM and Storage
