I like the idea of a plug-and-play emulation station in a retro-styled case, but that case design is copyright infringement territory. Emulation devices are on shaky enough legal ground as it is, we do not need to tempt fate
The 8600G is quite a leap ahead of the Steam Deck in terms of performance and architecture. But of course you can just take the steam deck with you and play on the go or in bed ;)
