I'm still a little suprised the Steam Controller is this popular. Aside from the trackpads (which is a big 'aside' to be clear) it's such a mid controller spec-wise.
What are people's use cases for the trackpads? I still swear by my OG Steam Controller and love the trackpads for playing, like, visual novels on Steam on my TV (through the OG Steam Link) or controlling my browser if I'm watching Patreon videos, but those are pretty niche uses.
