The evolution of aspect ratios---4:3, Cinemascope, Anamorphic, 70mm, etc.---is fascinating. There's a constant trade-off between aesthetic and technical requirements with a lot of really cool innovations for the time.
For my money the most interesting format is anamorphic[2].
I try to keep some notes.org file and use it regularly, but I'm just faster with unix tools and vim, so it's hard to make the upfront investment in learning emacs and start somewhat from scratch. I think there's also some kind of discoverability issue with org-mode features: I don't really know which features should I look into to improve my setup further and have something really nice instead of a glorified markdown.
One day I'll just read the manual from start to finish and try to start properly from there, one day.
I spend lots of time learning the tools I use for work (database systems, departmental protocols, client interactions) and having a better personal productivity tool is at the center of everything I do. It's worth months of heavy investment in the long run.
My files are 'logbook', 'life', 'project-1', 'project-2', etc. At any time I can hit a key and capture an idea/meeting to any of those places, and as I'm taking notes I can mark anything as a todo and schedule/deadline them. In the 'agenda' I can see a single overview of all my todo items, and my schedule, from all my notes.
I've tried a lot of systems (paper, apps, cli notes, etc) and org-mode clicks in a way nothing else has for me.
