I have a steam deck, and love using the device in handheld mode due to the trackpads. But I also like a bigger screen and prefer to play it docked to my TV.

When doing that, I miss the track pads and their value as a precise input or macro pad. There are some games that I have to play handheld because a controller doesn't give me enough options.

I didn't buy a steam controller yet, but it's absolutely on my wishlist for when I can justify it. Waiting on my old PS4 controller to bite the dust. Its trackpad is close, but not as good.

I think in a decade, we will see the Steam Controller trackpads redefining the default controller the way joysticks and bumpers/triggers did.
