I do a large chunk of my work in Evernote. Everything from outlining messages, writing blog articles, collecting illustrations, filing articles for reference, and collecting ideas of places to take or things to do for my wife.

If you want to see the practicality of it, Harvard Business Review used it for a recent study on multitasking.
