I’m a big fan of moleskine notebooks, which I seem to have settled on using after 15 years of searching for “the best” way to write/sketch on the go. They’re really good quality (especially the sketchbook one, that has great, thick paper), and get a lot of praise for their functionality (little pocket at the back for storing stuff, tough cover, elastic strap to hold it shut, integrated bookmark).
This guy bought a new version that’s made up JUST of pockets for storing stuff, and it didn’t quite meet his needs, so he hacked it. I like his change, but I hope Moleskine take note of his gripes with the original. If it’s not really that useful as it’s initially sold it may need a redesign, and I’d hate for them to stop focussing on perfection.
