I used drafts as the primary thing I type in.
http://agiletortoise.com/drafts/Often when I need to make a note, or save some piece of data I want to start writing as soon as possible. The app opens quickly, and you can tell it to start with a blank page every time. Then, after you're done typing you can send it to evernote, dropbox, facebook, email, or basically any other app or web service. For those who use a lot of text editors, you can tell it to append or prepend what you just typed to an existing file.
For instance, I remember a movie I want to see, I type in "Kiss Kiss Bang Bang" and then his "Add to watch list" and it adds the line "Kiss Kiss Bang Bang" to the end of my watch list file, then clears the screen.
