After crossing multiple sources considered to be safe and informed, the arstechnica site reveals that Valve has been developing a portable console for a while that could be ready at the end of the year, although it may be delayed (or even canceled).
Codename SteamPal
Codenamed SteamPal, the machine is actually a PC packed into a portable Switch-like enclosure: touchscreen, controllers, buttons and triggers, and even the ability to connect to a TV. Removable controllers are missing, however.
Objective simplicity of use
The console would allow access to the many games in the Steam catalog, to enjoy them in a simplified way compared to their computer version. With an attractive price and adequate communication, such a machine could find its audience. To be continued.
