Just tags plus dates would be enough to a very long way to making things much easier to organize. I know I made some notes after that meeting in October and I know I probably tagged the note with something like 'CFD' and/or 'wind'. Show me all the notes that match those criteria and I'll probably recognize the notes I'm looking for in less than a minute.

I mean physically, having to move several times and being too crammed while taking classes, I have lost several classes of notes. Digitally it's always on dropbox/gdrive.

You can't grep paper.

just to clear up any possible confusion; don't expect text recognition.

it's probably the most requested feature, but it's a really, really hard problem.

but please send me a message at [email protected] if anyone have any tips about solutions to this (we're talking with a couple of vendors, but we might have missed some).

FroshKiller is right, a good search feature would make this device much more useful.

Regarding that I do have a 'tip' for you. There is no need for an intermediate textual representation. If a sequence of pen strokes is what you have recorded, then a sequence of pen strokes is what you should search by.

For further tips (or an algorithm) I have to charge :)

Yeah, to be clear, I was talking about the advantages of electronic documents over paper in general, not any specific application of this device.
