Simplenote. It would be nice if it allowed me to attach images or other files, but it plays nicely with every device I have, and makes it easy to jot things down. The other tool I use is the Remember app on my phone, but only because it allows indexable voice messages. Hit the button, say my piece, and it's there for me later. A quick aide memoire when I'm on the go.
