I've read up about a few prior attempts. Apparently the problem is, although they are 'flexible', the connections/etc tend to crack if you flex them a lot. For example there was one where some sort of update-able screen thing was 'printed' on a cloth backing (a tee shirt, I think it was), and for the demo they would roll up the cloth (very carefully, though that wasn't obvious). After a few demos the surface of the thing would start crackling along the angles it had been rolled.
I'd be happy if they would print the 'flexible' surface onto a really thin, stiff backing. Or make one that folds in half or in thirds. (it would only have to flex at that the hinge points, and the circuitry could be extra tough there). But I suppose there's some other problem with that - cost, maybe.
