Yeah, I have Simplenote on my devices so that my plain text notes are always synced. Movies and TV shows we intend to watch, stuff to get at the store, unlock codes for lockers in the mail room of our building, stuff to discuss with my therapist, records I wanna find and buy, etc. I was at a show last night (Santigold and she kicked ass) and was jotting reminders for myself between songs. Having an instant notes repository is awesome.
Oh, I love this idea so much.
