I have a Deck and almost never use the track pads, they feel totally redundant to me. The right one is pretty good on desktop mode and in games that aren't Deck-optimized and need a mouse, though. What are you using both of them for?
Even for emulators, they're great for binding all kinds of extra functions.
Using the right trackpad also means I can free up the right joystick for other stuff, and there's always enough other stuff I want to access regularly enough.
Rollercoaster Tycoon, FTL, point and click games are games the trackpad has vastly improved for me.
This reads like "I never play mouse driven games"
