What's the point of making functionally identical knockoffs from "old-fashioned materials"? There's no difference between a smart notebook made of leaves of e-paper and a smart notebook (somehow, magically) made of wood pulp. Surely you're aware that digital pens are a thing if you really hate touch screens that much?
Since this isn't asking about materials so much as "what it looks like", I'll share my ideas (for the mid-late 21st century, the basic keyboard and monitor layout likely won't change much until then). So I'm picturing something like a hyper-thin (millimeter scale) sheet that's flexible enough to be rolled up and stashed away when not in use, rather like a scroll. It'll likely use biometric locks instead of passwords, which is more secure for everyone involved--you can't forget your fingerprint and someone else can't guess it. When you turn it on, it generates a holographic field like this. Instead of a two-dimensional desktop, you're now looking at a three-dimensional desktop. There will be advanced gesture control, so opening a file is just reaching in and touching it. You could also drag things on the screen around and shift their orientation. We probably wouldn't call it a "screen" anymore, but something more three-dimensional, perhaps a "field". Verbal control would also be an option. Any personal assistants would be at least on par with DeepMind, or slightly better. Nothing too fancy, it's supposed to be an assistant, not a cutting-edge research ai. Due to their portability, it would be easy to store lots of machines with different configurations and hardware--I could likely fit half a dozen in my drawer.
Might expand upon this in my blog.
