Project Q is the upcoming streaming only device that will allow you to play games installed on a PlayStation 5 remotely.
It has not been announced if the handheld will allow streaming of games from the cloud and is rumoured to cost between £250 - £300.
Will you be picking one up later this year?
You can, but the usability does suffer a bit. I would honestly just keep SteamOS on it as you will get better performance even with the compatibility layer, and you don’t really have to touch the desktop if you don’t want to. The Deck boots directly to steam.
So it’s not really a practical replacement for a PC? Damn.
It definitely is. You can try out the default OS, which functions just fine as a full PC in desktop mode or as a gaming console in game mode. You can switch between the two modes as much as you want.
But if you run into game compatibility issues or just cannot get used to Linux for whatever reason, you can install Windows on it. Again, you can use it as a full PC with Windows.
