EverNote is Jef Raskin's Canon Cat

In 2000, Jef Raskin wrote a book called The Humane Interface on user-interface design, and one of his visionary examples was the Canon Cat - an ideal computer that had no concept of files or filenames. Rather, you simply turned it on and started typing. I've always thought mandatory filenames an unnecessary burden.

Well, after using the free version of EverNote for a couple of years, I can confidently say that this is the modern equivalent of Jef's Canon Cat. If you have a thought and want to jot it down, or are in the middle of a phone call and need to write down some information, you switch to EverNote with Ctrl+Alt+N (it appears instantly) and start typing. There are no filenames to think up, and no need to save (it saves automatically). The EverNote people call their product an "endless tape", and you can use its incremental search to find old notes.
