Owning and still loving the Steam Controller, the haptic concaved trackpads could be set up to really feel like a trackball and, in my opinion, had all the benefits of the trackball without the downsides.

I also use a Steam controller. I like the touchpad so much that I wish there was a stand alone one that I could use for day-to-day computing activities instead of having a physical ball.

I know there are square touchpads you can buy for pointing devices, but the ergonomics are completely different. They are more replacements for finger trackballs rather than thumb trackballs. Like just give me a Logitech MX Ergo with the pad.
