>>3013801No, but I might use an OG Gameboy if I had any interest in a) playing video games or b) riding a bus, and it would probably be about the same size as the GA.
Aside from being a little boxier in the top corner with the viewfinder, it's no bigger than a DSLR, and still much shallower, thanks to no mirror and the lense not protruding from the body. It will happily fit into a satchel without being a big lumpy mess.
