My answer to that is to get a stand alone bluetooth keyboard. Most of the time I'm typing on my iPad is spent leaning back in my chair with my legs propped up, my mag cover holding my iPad up on the desk in front of me, and my keyboard in my lap. It's surprisingly comfortable, though it's probably wreaking havok on my lower back.
If I want to use the iPad as a tablet, I just put the keyboard down, and pick the iPad up. Pretty simple, pretty smooth, pretty nice. The only relatively small downside is if I want to type something while I'm out running around, I have to drag the keyboard along with me. But that isn't that big of a deal.
