I have the Steam Deck, I mean, I had it, because I'm waiting for the RMA because mine had a nasty bug which capped either CPU or GPU at a low level. And this is my message to you: Beware it is pretty much a beta product, so buy it with this in mind. You will experience lot of bugs and troubleshooting, specially if you want to use it outside Steam's box (custom mods, emulator's etc).
