Maybe you know about the LiveScribe SmartPen:

This was a really nice product, until the company decided to go for the "smartphone app" experience and changed everything about it drastically. I sought out and bought the older version (the second gen) because it actually had all the features I expected.

The concept is out there, but with the following improvements you can get the experience you seek: make the pen slimmer and more natural to hold, make the special paper look more like normal paper, and have a pen dock which does all the magic of syncing and creation of digital notes etc. Bonus if it were somehow possible to replicate the pixelation of the special notebook on a carbon-paper style sheet so that you can just use whatever notebook you wanted and insert this special sheet underneath.

Also about random access: I have always wondered why the eReader software never has a mode where when you scroll on the play head, it shows the current page, plus 2 pages before and 3 after (all displayed as smaller thumbnails, sort of like Netflix). Wouldn't that be at least a little closer to the flipping experience?

Stuff like the LiveScribe is close, but not quite, what I want. I think at the moment one of the most likely candidates is actually something with AR. Plus, it would just be really stupendously cool to have a blank notebook that is "full" of AR writing.

Talk about invisible ink.
