For Deck, we're vastly improving Proton's game compatibility and support for anti-cheat solutions by working directly with the vendors. “Hold on to your butts!”

The new version of SteamOS is optimized for handheld gaming, and it won't get in your way with other stuff. But if you want to get your hands dirty, head on out to the desktop.

Yes. Steam Deck is a PC, and players will be able to install whatever they like, including other OSes.

Așa este. Poți instala Windows 10 în loc de SteamOS. Dar de ce să faci asta dacă SteamOs vine cu Proton? Cât spațiu de stocare ocupă W10? Cât costă o licență de W10? Ai nevoie de moduri în W10? Optimizare? Rămâne de văzut cum rulează cu W10, drivere, latență, touchscreen etc.
