Nothing compares with the fluidity of longhand. You shift things around without shifting them around — in that you merely indicate a possibility while your original thought is still there. The trouble with a computer is that what you come out with has no memory, no provenance, no history — the little cursor, or whatever it’s called, that wobbles around the middle of the screen falsely gives you the impression that you’re thinking. Even when you’re not.
