I've thought about a similar idea before in the more minor context of stuff like note-taking apps -- when you're taking notes in a paper notebook, you can take notes in whatever format you want, you can add little pictures or diagrams or whatever, arranged however you want. Heck, you can write sheet music notation. When you're taking notes in an app, you can basically just write paragraphs of text, or bullet points, and maybe add pictures in some limited predefined locations if you're lucky.

Obviously you get some advantages in exchange for the restrictive format (you can sync/back up things to the internet! you can search through your notes! etc) but it's by no means a strict upgrade, it's more of a tradeoff with advantages and disadvantages. I think we tend to frame technological solutions like this as though they were strict upgrades, and often we aren't so willing to look at what is being lost in the tradeoff.
