One other thing that hasn't been mentioned is that with the order of each kit, you get *the latest* plans in full-size. It doesn't happen often, but occasionally one or a few of the plans get updated to a new version, and your preview plans will be out of date.
That said, I found the printed version to be very useful. I oftentimes prefer paper versions of things so that I can flip between pages, etc. I'm certainly not computer illiterate or a troglodyte

, but there are times when paper can be better for me. Easier to scribble notes on, as well.
If they don't work for you, stick the binder on the shelf and add it to your collection of airplane manuals, binders, installation manuals, maintenance logs, etc., etc.
