I would allow the setup to force me to carry a computer screen around, as long as it rolled up and fit inside something the size of a pen and had touch input when unrolled. As long as it had no local storage. Sounds just right, though I'm not entirely sure about the networked data, I guess that is probably the way the world will go. If everything is on the network, there's not much need for local storage.
