There are a few machines designed be similar experiences:

There's something called the Maximite, which is a single IC computer running BASIC with output to VGA and SD storage (http://geoffg.net/maximite.html)

There's something called 'petite computer' for Nintendo DS (http://www.petitcomputer.com/)

But it'd be great if someone started a hub for this kind of thing.
