Well, I need to get this as well. I had a thought after I saw this. I'm going to take my SNES and NES classic, that tiny Genesis mini, and this... and just stick them all in my backpack.. and still have plenty of room. Teen-aged me's mind would explode.
Wait... what if I cram this and the SNES mini together... would I make an SNES CD mini?
I think I really like the mini retro game system concept.
