The biggest push may indeed come from the Steam Deck. A PC in a handheld form factor, that allows you to hook it up to a monitor for a full KDE Plasma desktop experience. Very exciting. If we see a lot of people enjoy it and the Steam Deck is a success, you can be almost guaranteed that more devices will come along and slap SteamOS 3 on it and then also have a KDE Plasma desktop available.
Yeah the whole flash media and configure bios step is what gets people. If it comes preinstalled and the distro is stable you can just play with it. I think the decks gonna be real big for this experience.
