All I hope for is that the Controller fits well in my long thin hands - like the fat Steam Controller does.

With the right joystick in place, it’s certainly a product I may buy. The Steam Controller trackpad was not a sufficient alternative for joystick input when most games designed input with the right joystick in mind. Aiming and camera control with a variable and non-tactile deadzone and input default of trackpad camera controls has always been annoying to me.
