I'd be quite interested to try designing a game for it. Not something obvious like sudoku or crossword puzzles (nice though those will hopefully be if they get made) but an actual dynamic video game.
Of course it couldn't be anything much like existing games on account of the slowness of the screen update, but I'd quite like the challenge of adapting or originating a design which accommodated that. Limitations can force designers to be more creative in order to get around them - I started game programming back in the days of 4K RAM machines and getting a satisfying game into such a tiny space was to me an interesting and rewarding challenge.
I'll be interested to see if and when the SDK becomes readily available. I'd need to be able to explore a bit to find out what the limitations are and what would be feasible, but I've got a couple of half ideas lying around already
