Good Replacement of Mouse on a Personal Computer?
The short answer is, no.
What happens if you plug it in on a personal computer and use it as a mouse? Is it plug and play? What are the default actions of the touchpads and joystick and buttons, without installing a driver?
Here's one of the user Frenzie (on 2020-02-24) says:
The Steam controller works out of the box as a mouse, but then it's somewhat crappy. It needs Steam running to be decent.
Without Steam running, the right touchpad is the mouse and the left touchpad is nothing. The triggers click, but only if you press them fully.
With Steam running the right touchpad is a much better mouse/trackball and the left touchpad is for circular scrolling (out of the box; of course you can customize, but again, only with Steam running).
Good for Gaming?
For gamers, you probably won't like it. Either go with a keyboard + mouse, or, traditional controller. Many gamer's reviews simply said you couldn't aim well with the trackpad.
Here is a video of a funny gamer, reviewing the thing, and showing how it works in different kind of games.
