The notebook? Honestly, it has special features, and I like that about it. It's reasonably sturdy for a paper cover, has a stitched binding (as opposed to stapled), looks nice, and has plain old lined pages in it. I've tried other pocket notebooks that have special templates for todo lists on the pages, and I've ended up preferring just regular, lined pages. Makes for better free-form use.
I don't use a fountain pen for small pocket notebooks, but if you do, the paper is fountain pen friendly. It's the same paper that they use in their larger versions of this notebook.
The one feature I kind of wish it had was some perforated pages in the back for tearing out. But I can live without that. I could also just buy a perforating tool and give it some perforations myself.
