Simon Janes I use paper. I mean really use it. Making digital backups of my pages. One thing you have to do when you use paper, set and forget about changing your formats. Using 10.5"x8" binder paper (aka loose-leaf filler paper) of substantial weight. When you use both sides of the paper, you really cannot afford to use cheap paper. Lined or not, what really matters is consistent size and weight of the paper. But like a binder, I don't want to fiddle with PDF tools---what I have discovered is the digital "Comic Book" format is perfect for this. Using 7z, you can make a .cb7 archive which is just your images. A digital binder.

Eric Use it for what? What are you putting on this paper?

Simon Janes Free form notes, sketches, diagrams. Things that for the same reasons why paper books are often superior for. You can more often than not, write it down faster on paper than fighting with digital tools, tablets, &c.
