Thank you! It's been a long time since I tried Task warrior, so I might be quite off. Two main things come to mind: I realized that most task management apps offered many features that fooled me into spending time on organizing my data instead of doing my tasks. Tags, sub-tasks, projects, reminders, due dates. For me (and it could be a very personal thing) all these features became a hurdle as I was spending time trying to figure out how to tag my task or rethinking my hierarchies etc. I realized I wanted a system that does less.

The second thing that comes to mind is the extensibility that comes for free when every task is a file. I can easily copy an email to my todo folder and now it is a task. I can delete a task with `rm`. The fact that the notes themselves actually have absolutely noting to do with the management system is something that I experience as a very nice advantage.
