Raspberry Pi 500+ boasts a high-quality mechanical keyboard with removable keycaps and individually addressable RGB LEDs, an internal M.2 socket pre-fitted with a 256GB Raspberry Pi SSD, and 16GB of RAM.
I can do emulation with a regular keyboardless rpi connected to my tv. You want portable emulation? I do that with a gpi case, and runs on batteries! This weird desktop approach is what doesn't make any sense to me.
I could stream a beefier PC to it with sunshine/moonlight maybe and use it as some kind of really light desktop, but still, why would I do that and not just have the beefier PC in said desk.
