I have been looking for reasonably priced Flexable keyboards for my CF-01, I stumbled across Plycon.com, they import colored flexable keyboards from Japan. The price is about $50 USD, I've seen others sell for over $100 USD.

You might want to check at a local computer show. We had one last weekend and I saw the blue version of those keyboards for $34.95. I didn't get one, I just couldn't think of any use I really had for one. They are pretty interesting though. Remember that you need a hard flat surface to use it since it has no stiffness in itself. I am usually using a keyboard balanced on my leg so this would not work fo rme very well.
BTW, I just realized the guy is selling them on his web site, too, for $35.00, so you don't have to get them through eBay. He says the retail price on these is $69.99. Here's the link:
