This is possibly a very strange question, and I'm not sure where to ask it! But is there anyone around that uses a standing desk or a treadmill desk, and can you tell us how it effects your productivity and your typing. Do you make more mistakes? Do you use a tramill when you're thinking, or reading? Does it make you more or less effective? I know it seems like a stupid question, but I am very serious, and very keen to find out peoples thoughts on the matter!
