As an art oriented individual, I agree totally with Neko.
The dream for an A4 colo(u)r touch sensitive eink device is what keeps me searching since the first Mac in 84. It would fulfil all my ewishes. Where's that efairy!
Oh! No one said anything about digitizing those beautiful coffee table books. It's because nothing exists to display them. Colo(u)r is truly necessary for that. And if it's eink, it could be displayed at a specific page indefinitely!
