San Francisco's writerer community is nothing if not entrepreneurially twee as a mofo:
Typing Writer is about getting words on the page. It comes loaded with first drafts from some of your favorite writers: Jim Shepard, Melissa Febos, Amy Brill, Tao Lin, Rick Moody, Eli Horowitz, and Stephen Elliott (that's me).
It works just like your old typewriter. When you type over something you still see the original letter underneath. When you reach the end of a line, if you don't manually go to the next line, the typewriter will go to the next line for you, even in the middle of a word! Press your finger on the page and a white-out brush appears. Brush over a letter or a word. There will still be a white splotch, of course. That's how white-out works!
If you pay $1.99 for this, you are the machine.
