Just a notice about the talk of the other day about android : raine would work almost out of the box on the steam deck, it's an amd cpu, running linux arch, and this is what is supported here by default !
Ok, it's not like using a phone which is already useful for some other uses, but for those interested, it just works. I don't own one so I can't give some step by step instructions on how to install, but it's probably quite easy. It's probably worth mentioning this !
