I have a hybrid system. I use a combination of both depending on context. In the end though, it all gets loaded into Obsidian unless it is work related. It makes it easier to decide what is important enough to keep and archive in a searchable format.
Usually something very information heavy like lectures will go directly to digital. I have a hard time keeping up in a legible way if I try to do it by hand.
Fast notes and anything that I can take my time with will go onto pen and paper. Same with when I’m away from my desk. I hate taking notes with my phone in general. The only exception is if the note contains a URL beyond the basic name.domain type deals. I do this stuff by hand because scribbling a note when I’m out is faster than getting the phone out and opening a notes app. When I’m at the desk, it is just nice to slow down and think about what I’m writing some times. Other times it’s just easier to grab a writing utensil and scribble down contact information in a full screen application or on the phone.
