What? The Steam Deck needs trackpads and L4, L5, R4, and R5 buttons! Without them I wouldn't have been able to play modded Minecraft properly due to the amount of controls introduced by the mods I use.
If they ever drop the track pads I'm out. It's the only reason I got the Steam Deck as I play a lot of WoW on it and they are basically required. Plus I tinker in Linux a ton too and also they are super necessary.
