I have a GrandTec silicone keyboard that completely lights up.
The Pros: easy to transport, just roll it up and off you go. lightweight, water resistant.
The Cons: key press action not as good as a regular keyboard. It is flexible, so it has to be on a hard surface, cannot be used
on a lap without a supporting pad or table.
The one I have lights up, so it as a great coolness factor, especially in a dark typing situation. Ever since I first saw one in Die Hard 4, I had to try one, and a friend got me the lighted one as a gift.
I'm not sure if this is worth the cost, but okay if someone buys it for you as a gift.
