I really don't think I can say enough good things about the Steam Deck. If you haven't seen it, they have even supported the device helping people install Windows on it.
I am aware that Valve has done some shady stuff in the past. Given time, I'm sure they will do more in the future. Today, though, they are such a breath of fresh air for the support they have shown.
