When someone says "portable," what do you think? I think "fits in a bag or pocket," but some people would go the "portable" generator route and say "is not physically fixed in position." That seems to be the "portable" that the creators of the SNEGENES had in mind when they said their device was so. Now, I don't want to detract from the obvious glory of what has been created here: a (technically) handheld device that will play cartridges from NES, SNES, and Genesis — but really, that thing is about as portable as my bathtub.
