I've been an Emacs user since 2000 or so. Got introduced to org when it first came out and it (along with ledger for accounts) have taken over my life.

The phone did make it a little challenging but before that I used a notebook and dumped it into org at the end of the day. I've been doing something similar with my phone now.

A lot of people refer to org-mode as the gateway drug for Emacs and it truly is that.
