I love natural light. You are amidst a great love affair between natural light and I. From the great amount of photographers that I know I get the impression that a vast majority of them feel the same way about it as I do about studio lightings.
It's not that I don't like studio lights. It's just that natural light is so beautiful, so perfect and comes so easily to me. In the UK it can be extremely hard to control natural light and in the middle of winter there is VERY little to work with so this is why alot of people choose studio lighting. As I see it studio lights mimic sunlight and natural light... so why not skip the middle man and work with the original light source directly?
Seriously... I love it.
Just. Love. It.
Once you have tamed the natural light beast, then studio lights come easily if you chose to go that way. And if not then you have a free, gorgeous, rarely failing light source.
