old systems new software? (Score 2, Interesting)

It would be interesting to see a unit like this come with some simple card reader (similar to the GBA eCard reader) so that new games could be written for the platform. I mean, at $20 people will buy it. Downloads would be printed and scanned in. I realize this is mostly a geek thing, but the interest to me is that this is a very small and constrained system and that by itself makes it interesting to program for.
