I wrote my own Evernote style system and used it for a while. Then I changed to my current system: Emacs and org-mode for notes, todos, tasks, etc. I also use Notes in Fastmail (and they show up in Apple Notes automatically). For PDFs of purchased books, Communication of the ACM, good articles converted to PDFs, etc. I use Google Drive because it is searchable.

By searchable you mean Google Drive can search _inside_ of documents like PDFs and images?

I don't think search works inside images but works well for PDFs. Just this morning I was trying to find a particular paper on LSTMs and NLP and I found what I needed very quickly.
