I kinda dig it. I have comically large hands so the big chunky controllers appeal to me. Don't think I'd ever use them detached but if there's a connector thing like for joycons I can see it working.

Why do these people design the control interfaces without giving thought to it that if it's for PC gaming, mouse cursor control is paramount? While this has a touchpad, the position look like it's an afterthought. And doubly so if it's going to run on Windows on a small screen; touch is just about doable on a 12" Surface Pro screen, I can't imagine going smaller than 10".

Wow, that looks awful as a handheld.

Why are the back buttons on the right controller aligned horizontally while the left controller back buttons are aligned vertically?

Also there are two side bottoms shown as well. I'd love to see a demo of this in action.
