There's a product called The Noteboard [1] that's relevant here. It's basically a 7x5 grid of index cards laminated to be a whiteboard that you can toss in your backpack. I didn't end up using it regularly because the surface doesn't erase as well as a whiteboard, but still a cool product. [1]: http://thenoteboard.com http://thenoteboard.com
