This is from the article:
“This was the turning point for me, where I went from “well this is kind of neat,” to “this is actually rad.” There I was, playing FF7R from the PS5 in my house in a cafe across town and it was nearly indistinguishable from the experience at home. Again, that’s something that can certainly be done on your phone or tablet (and those are able to get past that login screen) but none of them feels as good to hold and play on as the Portal.”
It does play via remote wifi but only games from your local ps5.
So the remote play functionality from before remains intact. So once paired with the PS5 the device can remotely turn the device on or the device is always listening for the connection.
This is a dedicated device for that though. If you read my initial post I’m not a fan of the device and even less of the manner by which IGN reviewed it. They’re looking at it in a complete vacuum and comparing it to a device that basically already failed (The Backbone).
