I figure it will be a good thing to throw onto a wish list for whatever holiday is coming next. In a perfect world, it would run a Linux-based OS, be moddable, have decent ergonomics for an adult, and kinda just generally not suck. Is a hundred bucks a reasonable price point? One hundred fifty? I grew up in the 8-bit and 16-bit eras but never completely stopped gaming, so I'd be interested in emulating somewhat newer stuff too. I normally just plug in a controller and find a desktop emulator, but portable could be fun, especially if it had potential for general SBC computing.

Edit: I think I have a better idea what I'm looking for now. The Anbernic devices seem to more or less match up with what I am looking for, so I'll start there with a more informed search. Thanks! Happy to get more suggestions and tips, though.
