Well said and I agree. Everything most e-ink tablets do you can already do with paper and pencil, more or less. You can search your notes on the tablet, you can search your notes in a paper notebook, and with the paper notebook you can remember things like "it's towards the back, after X". You can manually tag your e-notes, reality automatically tags your physical notes with things like page wrinkles and spilled coffee stains. So, slightly different but ultimately quite similar for most people.

Again, I think spaced repetition is a killer feature that could finally distinguish an e-ink tablet from paper. I think this idea has more potential for improving learning than almost all the multi-million dollar learning websites out there. It can systematically take you to savant levels of recollection in any topic. And right now this tool is locked behind some clunky text focused UI. (Yes, latex and pictures exist, but they suck when compared to drawing on a page.)
