Ironically enough, it's led to me playing more games on the living room television! The steam deck helped me adapt to playing with a gamepad, as opposed to mouse and keyboard.
Until they come out with a Steam Controller 2, I will say the best gamepad for steam is the Dualsense (a Dualshock 4 also works). It's got one touchpad instead of two, but Steam lets you map the left and right half separately, which covers my primary use cases. I also installed the RISE4 remap kit, a hardware mod that adds paddles on the back of the controller which can mimic any face button. Not as good as having actual new buttons, but it does mean I can run and jump without taking my thumb off the right stick.
