As a reminder, the PlayStation Portal, or Project Q, is (according to leaks) based on Android. It doesn’t run the games itself, it merely streams them from your PS5 and your handheld then serves as a controller with its own display.
I’m wondering why anyone would prefer that over simply using a regular Android phone with a good controller and the PS Remote Play app?
Depends what SOC is in it. Since it’s only streaming video it’s probably a pretty shitty one that wouldn’t emulate much beyond 16 bit.
