From the photos, it doesn't look like anything super special. I carry a couple Rite-in-the-Rain notepads around, which are waterproof and not very expensive. They go everywhere with me. I am very clumsy at times, and can tell you that not only are they water proof, they are also Fixer proof =P.
If I want organized, uniform columns, I break out the straight edge and label things by hand. That whey I have space for what I need, and nothing more.
