There are hundreds of millions of PSPs, Vitas, DSes, 3DSes, Gameboys, etc floating around in the hands (or closets) of actual users out there.
Those are consoles that are fully hacked, with high quality open source toolchains and SDKs, and emulators.
If you have a retro handheld game development itch, those will scratch it better than anything else, especially since there’s a real chance people will actually play your game.
Developing for those old consoles also means you potentially delay them going to a landfill.
Not to say the gadget in OP isn’t worth buying, but the “indie dev” value proposition isn’t that strong IMO.
