If you have a Mac you have TextEdit, the uber simple word processing program. I use TextEdit all the time to write down thoughts, to compose Assignment Houston write ups, to save random things. TextEdit is great. And now I love it just that much more.
I found out today thanks to the genius of Twitter that this is what is lurking on the icon of TextEdit. I didn't know! You have to pull the graphics up on the icon to see it and who would ever think of doing that. Nobody except Steve Jobs.
