You know, that would be a good idea. Not that I think it would happen, but you could make a newer, tiny TE, and it could have an internal 64 meg or so chip that holds nearly every single good hucard known to man, and it could probably be sold dirt cheap. Market it like the Atari/Sega multigame systems and I think it could do really well.
I got a TE and a flash card so I could do this very thing, but it wasn't dirt cheap.
