There is definitely a sweetspot. I understand 4 inches is very small for any mildly serious task, it can be done but it's painful. But IMO 5 or 6 inches don't feel so liberating. It's better, but not that much, and at the end of the day I really want an iPad to do any task that will last more than 5 min. For people who usually have a carry bag, an iPad is not so big or clunky. Having a 4 inch phone to pocket is then good enough.
