I see an awful lot of people in our community that have changed from ring bound planners to the travellers notebook style notebooks for planning and note taking.
I use quite a combination myself. Here are my daily planners/organisers On the left is my Quo Vadis Daily 21, which I use as my journal with my Van der Spek pen case, I only write in fountain pen in my journal. Then my Van der Spek A5 Manager custom which is my main stay planner and tool for organising tasks and appointments. And then on the right is my Van der Spek Nomad regular size travellers note book, this is purely used for notes for each episode of the podcast.
As they say... it is pen and paper so does it matter how it is assembled and how it functions? Not really.
For those of you who also have a 'foot in both camps' I also host the 'Travellers Notebook Times' blog which mainly features a once a week 'Web Finds' post just like here on Philofaxy but for Travellers Notebooks. I have done some reviews as well and we feature new product announcements too.
So do you use a combination of paper and pen formats like I do?
