The negative points are pretty much why I haven’t used paper notebooks very much since my teens. Having a pile of stuff to sort, revise, and remove the cruft from: is a problem that doesn’t scale. Or as I like to remember: after about three binders, I’m pretty much done and hate dealing with heaps of folders.
Most of the advantages I sought came from having a digital file system. Typewriters never really did it for me the way text edited and word processors do. But as a consequence of funneling everything down the word hole: you lose the freedom of the page.
One of the things I’ve enjoyed about having tablets is the ability to have my tablet alongside as I work. Lean over, and swipe words into my textual notes, and then shift back to my work. Evernote also works pretty well in that it optimizes for the more word processor like nature of many of my work notes, yet makes it easy to merge disparate bits of information from external resources. Including handwriting, images, documents, scripts, etc.
Tablets open up greater ease to get off the beaten path of the word processor: while retaining the ability to keep it as simple as WordStar. Especially when you have both a stylus and a keyboard available to aide your note taking.
