I've been a big fan of digital documentation for quite some time. I was an early adopter of PDA's, with Palm Pilot V and Mitac Mio-168 before settling on iPhones ... Before then I was a firm user of Filofax binders.
Sometimes there is just no substitute for dead-tree edition. Propper were kind enough to send me a set of pocket-sized notebooks in my recent delivery, and I've had one sitting along side my iPhone in my Hazard4 Escape RG harness and beside my passports.
I could tear this page out, and take it with me, pass it to a friend, eat, burn or whatever.
The 48 pages are grid printed, and whilst the grids aren't either in fractional cm or inch increments, they are nicely uniform and pleasant to write on. They aren't waterproofed like the pages of a Rite in the Rain notepad, and could even be used as kindling, in a pinch.
Notepads, still not a dead technology, and better yet, they never run our of battery or need software upgrades.
