I think we're focussing on two different perspectives. The method isn't meant to replace a meter at all. It was developed before meteres were widely used by hobbiests and weren't always included in consumer cameras. What it is useful and I believe still relevant about Sunny 16 is for teaching photographers to learn about light and exposure if they don't already. But you can still take awesome pictures and most certainly more accurately exposed pictures with modern cameras by just put them on Program and shoot away. Doesn't mean its not both a useful tool to use sometimes and is very useful to getting a sense of different kinds of light and how it effects exposure. I think its probably a good idea for someone who is beginning and hasn't had a lot experience to learn it, and use it intensively for a week or two. You can learn a lot, even if you think you already know it.
