Doesn't the steam deck use micro SD cards, I don't think that these full-sized ones are going to be much help for those guys. Unless of course they come out with stainless steel micro SD cards but that doesn't seem likely for obvious reasons.

I guess if they made the chips small enough that the MicroSD body is just a shell, same thing happened with full sized SD cards (there was a time the whole space inside them was used, now it's usually a small part of the front and the rest is just the body shape for compatibility).
