A Deck has two touchpads that work as mice.

And they suck trying to use them for an FPS.

Only time will tell.

No way in hell Nintendo would come out and talk about exploits in their game console. Also if they knew about it they’d fix it first.

Also wouldn’t this be directing a ton of money to google? (or I guess any other ad provider)

Is it more confusing than dealing with splitscreen/dual screen android? Two distinct devices sounds easier to me honestly.

While good for privacy, this sounds like an awful UX change for the average person. Some sort of nice toggle to disable it would be good, but removing it all together would probably annoy more people than it benefits.
