Ideally you'd want 2 zoom factors, one for visuals and one for touch. But then you'd potentially have buttons that couldn't hold their labels anymore. I think one zoom factor should be sufficient. Given that we can't support actual-size rulers today, I think we've demonstrated that we can live without them. P.S. for low resolution displays it's obvious that clear text and graphics is more important than absolute size.
